Southern California’s Blu returns today with a little help from a couple of labelmates. Blu trades verses with fellow Nature Sounds artists R.A. the Rugged Man and Durag Dynasty’s Tristate over a crackling sample on his latest track, “Thelonius King.”

Give that a listen below and look out for more from all three rappers later this year.
