“We got London on the track” is the famous drop, spoken by Skooly of the Atlanta rap group Rich Kidz, that helped turn producer London Holmes into a brand name. But it was one of the group’s contemporaries, Young Thug, that brought London On Da Track’s beats to the Hot 100 with a series of hit collaborations with Rich Gang, Tyga, T.I. and others. And over the course of Thug’s solo releases, particularly the Slime Season series, London On Da Track has emerged as the rapper’s most indispensable producer. His rich piano chords, swirling synth lines, and crisp, swinging percussion provide the musical heft for Young Thug’s best songs, allowing the iconoclastic rapper to experiment with his elastic voice over a solid foundation.

Producer Xavier “Zaytoven” Dotson has been instrumental in shaping the sound of Atlanta trap music as an early ally of Gucci Mane and Migos. But perhaps his most revered work is Future’s 2015 mixtape Beast Mode. At the time, Future’s friend DJ Esco was locked up abroad with the hard drive containing all of the rapper’s unreleased music. So Future entered the studio with Zaytoven, and in three days recorded what became Beast Mode, one of a trio of acclaimed mixtapes the MC released in the space of a few months. And in 2018, it’s rumored that Future and Zaytoven will reunite for the long-promised sequel, Beast Mode 2.Future and Zaytoven first crossed paths on Free Bricks, the 2011 collaborative mixtape by Gucci Mane and Future. And the chemistry between Future’s throaty melodies and Zay’s lush piano and flute loops was cemented on 2012’s Astronaut Status, one of the mixtapes that built Future’s buzz before he began releasing major-label albums. Since then, Zaytoven has been a frequent presence on Future records, contributing a warmly melodic and relaxed sound that contrasts with the more aggressive textures of producers like Metro Boomin on chart-topping albums like 2015’s DS2 and 2017’s FUTURE.Future and Zaytoven’s biggest hits together include the tawdry Beast Mode highlight “Real Sisters,” the celebratory Drake collaboration “Used To This,” and “Too Much Sauce,” the Lil Uzi Vert-featuring single from DJ Esco’s 2016 mixtape Project E.T. The familiar sound of Future over a Zaytoven beat even opened “3500,” the epic lead single from Travis Scott’s debut album, Rodeo. But the duo’s dozens of collaborations include mixtape favorites of any Future aficionado, including “Just Like Bruddas,” “Space Cadets,” and the ominous, paranoid masterpiece “Feds Did A Sweep.”

Future’s career reached new heights in 2015 thanks to his prolific mixtape output, and he continued the pace in 2016. January brought the mixtape Purple Reign, which spun off one of his biggest solo hits, “Wicked,” and February brought the chart-topping album EVOL, with brooding favorites like “Low Life” featuring The Weeknd. He linked up with Lil Uzi Vert and Rich Homie Quan on the Future-dominated DJ Esco mixtape Esco Terrestrial, guested on hits by 21 Savage and A$AP Ferg, and continued his partnership with Drake beyond What A Time To Be Alive. But perhaps the biggest surprise of the year was that even Jay-Z wanted Future on the hook, for the DJ Khaled single “I Got The Keys.”

Marvel’s Luke Cage is a black superhero from New York with a conscience. And the creators of the hit Netflix series about him chose to name his adventures after after an appropriate musical inspiration. Each of the 13 episodes of the show’s first season are named after classic tracks by Gang Starr, the group that paired one of hip-hop’s greatest producers, DJ Premier, with Guru, the erudite and soulful MC who passed away in 2010. The Luke Cage episodes draw on song titles from the group’s first five albums, with a particular emphasis on their 1994 classic Hard To Earn, which featured tough guy anthems like “Code of the Streets” and “Suckas Need Bodyguards.”

For six decades, George Jones was one of country music’s most revered vocalists, as well as its most infamous alcoholic. And while his personal struggles with the bottle sometimes kept “No Show Jones” from the stage, it never seemed to hurt his golden voice or his prolific recording output. And songs about drinking, including celebrations as well as laments, became a significant theme in his catalog, from the rowdy 1959 pop chart breakthrough “White Lightning” to the tragic, Jones-penned 1976 album track “A Drunk Can’t Be A Man.” He even memorialized his infamous incident of drunk driving a riding mower with the 1996 hit “Honky Tonk Song.” Whether he was drinking alone or sharing a round with Merle Haggard or Willie Nelson, here are The Possum’s greatest songs about beer, wine, and moonshine.

Mary J. Blige burst on the scene in the early ‘90s as the “Queen of Hip-Hop Soul.” She sung beautifully over gritty breakbeats and traded rhymes with Grand Puba on the title track to 1992’s What’s The 411? In the decades since, Blige has collaborated with dozens of rappers, including hits by Ludacris and Common. And 1995’s “I’ll Be There For You/You’re All I Need To Get By” with Method Man stands as one of the most beloved duets by a rapper and an R&B singer of all time. And she’s even created a rapping alter ego, Brook Lynn, to flow on remixes of tracks by Cassidy and Busta Rhymes.

Every group has its breakout star, and for Atlanta rap trio Migos, Quavo has long been their Beyoncé. But as they rose to new commercial heights in 2017 with the chart-topping single “Bad and Boujee,” the spotlight shifted to another member, Offset. And that left Takeoff—who doesn’t appear on “Bad and Boujee” or the group’s hit Calvin Harris collaboration, “Slide”—looking like the odd man out. Takeoff even had to defend himself to an interviewer at the BET Awards, motioning to his impressive jewelry and asking, “Does it look like I was left off ‘Bad and Boujee’?”But Takeoff (a.k.a. Kirshnik Khari Ball) is nobody’s weakest link. In fact, he’s arguably the best MC in Migos, with a flair for vivid word choices and a distinctively raspy voice that contrasts with his uncle Quavo’s buoyantly melodic delivery. And he’s held down the chorus and first verse on some of the group’s hits, including the recent “T-Shirt” and 2014’s “Fight Night,” which was the highest charting Migos single before “Bad and Boujee.”Takeoff’s hoarse bark often recalls Rick Ross on the group’s most ominous trap anthems like “WOA” and “Cross the Country.” But the way he bites down on consonants with a percussive flow reminds me of Memphis legend MJG, another skilled rapper who was sometimes overshadowed by his partner 8Ball. And he’s displayed a facility for more light-hearted tracks like “Playa Playa,” and even made up for his absence from “Slide” with an appearance on Calvin Harris’ equally smooth “Holiday.” Takeoff released his first official solo track “Intruder” in 2017, and it’s an encouraging glimpse at how capable he is at holding down a song without the help of Quavo and Offset.

Jay Jenkins burst into national consciousness in 2005 as Young Jeezy, but a few years later the Atlanta rapper shortened his official handle to simply Jeezy. And he’s certainly not “young” anymore, as he turns 40 on September 28. For over a decade, Jeezy has stood with his friend T.I. and his collaborator-turned-foe Gucci Mane as one of the titans of trap music, the street-hustler variation on southern rap that has become one of modern Atlanta’s biggest cultural exports.With a hoarse but gregarious voice, Jeezy was at first more known for his ad libs than his rhymes, cackling “ha haaaa” and “yeahhhh” on his multiplatinum Def Jam debut Let’s Get It: Thug Motivation 101, and his group Boyz N Da Hood’s self-titled album, both in 2005. But there was also an unflinching darkness to his music that he retained even in crossover hits like the Akon collaboration “Soul Survivor.” And an unlikely political bent emerged in his music with the 2008 album The Recession, which contained hip-hop’s biggest unofficial Barack Obama anthem, “My President.”Jeezy The Snowman’s career has cooled off in the years since his rapid ascent to stardom, but he’s remained one of Atlanta trap’s most consistent hitmakers. He was early to adapt to new sounds like DJ Mustard’s west coast groove on “R.I.P.” and traded introspective bars with JAY Z on “Seen It All.” More recently, in 2016 he returned to the top of the charts with Trap Or Die 3 (a sequel to his 2005 breakthrough mixtape), which featured “All There,” a posthumous hit for the late Bankroll Fresh. And it’s hard to imagine Jeezy retiring anytime soon even as he marks another decade of life.

Chicago native Kanye West is one of midwest hip-hop’s biggest stars, and he made his name producing hits for JAY-Z and other New York rappers. But West has maintained his relevance over the years in part by keeping a finger on the pulse of southern hip-hop, drafting rising stars from Atlanta, Houston, and Miami to appear on his albums and producing hits for Dirty South stars like Ludacris and Jeezy. Most recently, he served as “executive producer” on Atlanta trio Migos’ new album, Culture II, where he co-produced the 21 Savage collaboration “BBO (Bad Bitches Only).”Kanye West’s track record below the Mason-Dixon line dates back to the late ‘90s and early 2000s, when he was a relatively unknown producer placing tracks with southern trailblazers like Goodie Mob and Scarface. In 2003, he notched his first No. 1 on the Hot 100 producing Ludacris’ club banger “Stand Up,” along with a pair of tracks on an album that would help define the next wave of southern rap, T.I.’s Trap Muzik. Over the next few years, as West became a solo star who bridged many divides in hip-hop, he became the kind of rare stylistic chameleon who could make trap hits with Jeezy or screwed ’n’ chopped grooves with Paul Wall in between his excursions into east-coast boom bap and futuristic EDM.As the founder of G.O.O.D. Music, Kanye West has signed Atlantans 2 Chainz and CyHi The Prynce, and helped mentor Houston rapper/producer Travis Scott. G.O.O.D.’s 2016 posse cut “Champions” brought together some of the above with Gucci Mane, Yo Gotti, and Quavo. Some of Kanye’s southern collaborations are better off forgotten, like the treacly Future duet “I Won” and the ill-fated Lex Luger-produced Watch The Throne single “H.A.M.” But by and large, Kanye West has been present for moments of greatness in southern rap, from Scarface’s The Fix to Lil Wayne’s Tha Carter III.

Young Thug says “Metro Boomin want some more,” Kodak Black says “Lil Metro on that beat,” and most famously, Future says, “If Young Metro don’t trust you, I’m gon’ shoot you.” Regardless of which rapper is identifying Leland “Metro Boomin” Wayne at the moment, odds are you’ve heard his name and his beats on the radio a lot in the last few years. The St. Louis native began driving to Atlanta to collaborate with musicians as a high school student. Since his flashy piano work on 2013’s “Karate Chop,” he’s been one of Future’s closest collaborators, and he’s slowly expanded his clientele across the music industry, from Kanye West to Nicki Minaj.Although Metro Boomin is a master of the heavy bass and busy hi-hat programming of Atlanta’s ubiquitous trap sound, his work isn’t as singular or distinctive as previous kings of the scene like Lex Luger and Mike WiLL Made-It. Instead, Metro has distinguished himself with the sheer variety of sounds that he’s integrated into the trap blueprint, from the haunting chords of “Bad and Boujee” by Migos to the ethereal flute sample of “Mask Off” by Future.Metro Boomin is also a big collaborator, crafting the woozy groove of ILoveMakonnen’s quirky hit “Tuesday” with Sonny Digital and working alongside three other producers on Big Sean’s “Bounce Back.” His ear for bringing together the contributions of others served him well as he executive produced Drake and Future’s hit collaborative album What A Time To Be Alive and 21 Savage’s breakthrough mixtape Savage Mode.
