Founded in the late ’00s, Glasgow’s Optimo Music is the quintessential Scottish label, and that’s exactly the way JD Twitch wants it. The producer, DJ, promoter, remixer, and proud Scot has amassed a catalog that directly mirrors the freely flowing exchange between DIY, anything-goes rock and cutting-edge dance music that has long defined the country’s underground. After all, Scottish artists were some of the very first on the planet to (1) blend punk and discoid propulsion (see Fire Engines’ 1980 landmark “Get Up and Use Me”), (2) fold alt-rock into house/techno (Primal Scream, of course), and (3) pioneer ’00s dance rock (the crazy prescient Yummy Fur did it a decade ahead of schedule).Among the slew of vinyl Twitch released in 2016 (including those sides on the Optimo Trax and Optimo Music Disco Plate sub-labels), it’s on The Pussy Mothers’ The Number 1 EP, MR TC’s Surf and Destroy, and Junto Club’s Warm Me Up that these deliciously anarchic qualities are most in your face. Surf and Destroy is especially telling: the title track is a throbbing orgy of acid squelch, post-punk atmosphere, and psychedelic guitar wash.In contrast, these qualities become more subtle on those records that (at first blush, at least) tilt more toward orthodox dancefloor groove. A track like “In Turbine,” from Underspreche’s Invito Alla Danza Part 1, is minimal, electroacoustic drone rock (complete with warm organ hum) from a duo who are no strangers to pounding club jams. Noo is another revealing example: Their Optimo Music Disco Plate Five is all about 21st-century Italo awesomeness filtered through a scrappy, slacker basement vibe. Noo, it has to be noted, was founded by Christophe “Daze” Dasen and Sami Liuski, who hail from Switzerland and Finland respectively. You see, that’s a part of Twitch’s curatorial genius; he possesses a knack for teaming up with artists who, while they may not hail from the Scottish underground, create music that totally reflects its unique sensibility.Note: while my playlist is stacked with tracks from Optimo Music’s 2016 releases, listeners will also discover a handful of older gems. Truth be told, the label’s full catalog is never far from my turntable. For example, I probably jam Golden Teacher’s Do Not Go Gentle Into That Good Night — a boisterous collision of future punk, acid, and all manner of tribal funkery released in 2013 — at least once a month. Like most underground music from Scotland, this stuff simply doesn’t age.
