Rapper, singer, self-taught multi-instrumentalist and producer Stefon Alexander has been doing business as the punk-influenced underground hip-hop artist P.O.S in Minneapolis since around the turn of the century. He’s one of the founding members of hip-hop collective Doomtree, while also finding time to be part of a punk band, Building Better Bombs, and another Twin Cities collective, indie rockers Gayngs. Fortunately, P.O.S (above, performing “Sleepdrone” live in studio for KEXP FM) continues to do solo work. His fifth full-length studio album, Chill, Dummy (stream it below), which features guest vocals by Justin Vernon, came out at the end of January. A.V. Club calls it “a record about surviving, living and battling for every little thing you’ve got—something P.O.S knows his fair share about.” And Pitchfork says Alexander “is still all about his consciousness, and usefully motivated by anger. But on Chill, Dummy, he embraces a freed-up feel, with some grooves you might hear in a club.” Now out on the road, the lyrical bomb-thrower plays Rough Trade NYC tomorrow night and Mercury Lounge on Wednesday. Rappers Ceschi Ramos and Transit22 open both shows.
