The tracks bounce between Chicago house and Italo-disco and have a nice sheen that belies a mid-period Detroit influence. They’re also quite well known for their influential blog, Feel My Bicep, which is a destination site for fans of underground electronic music. What It Sounds LikeThe original “Opal,” from Bicep’s self-titled 2017 album, is a sludgy chunk of flangy, metallic synth sounds and downtempo drums that is surprisingly melodic for the duo. Four Tet doesn’t tinker too much with the formula. As is his wont, Four Tet adds whirring ambient textures and isolates the track’s melody, adding a layer of distortion that draws out the tracks blurry qualities. The track takes a minute to build, but, by the end, it’s vintage Four Tet: both transcendent and completely ephemeral. Suggested Playlist PlacementHedonist Hangover Music.
