RP Boo has a storied, 30+ music career in Chicago, one of the highlights being his role in the creation of footwork. That's the genre Boo's working on for I'll Tell You What!, his new album for Planet Mu. "You gotta have some type of groove and you don't develop the groove overnight, you have to let it mold within you," Boo told The FADER last year. "I was born with it, but I didn't know how to describe it. But as I start producing the music, that was the way of it seeping out." Hear the groove in all its ecstatic colors and morose shapes below on Apple Music and Spotify.
