The rapper and producer P.O.S. – aka Stefon Alexander - has been a central figure on the thriving music scene in the Twin Cities in Minnesota for well over a decade. He’s a founding member of the hip hop collective Doomtree, and a punk rock guitarist and vocalist, all of which has kept him busy. But in 2012, P.O.S. had to back off his musical activities because of failing kidneys. He had a kidney transplant in 2014, and two years later reappeared with a single track. Now, he is back with a full-length album called Chill, Dummy, a reminder to himself as well as a way to make listeners think.
