Doomtree co-founder, punk philosopher and lyrical bomb-thrower Stefon Alexander, aka P.O.S makes tight, declamatory music that builds on the Minneapolis-bred rapper and producer’s penchant for grinding beats and radical lyrics. Known for welding hip-hop with guitar squalls, screamed vocals, and futuristic beats fit for a Berlin nightclub, P.O.S steps even further into genre-blurring territory with “sleepdrone/superposition,” a nearly nine-minute-long sprawling masterpiece that touches on “being black, beefs, loves, hurts, victories, pride and the future” all while reflecting over the past two years since a kidney surgery sidelined him from making music. It’s never felt better to have him back in action.
