Stones Throw signee Jonwayne aka The illest mc/producer in Birkenstocks recently was a guest performer at the L.A. edition of Boiler Room. Fresh off the release of his Cassette 2 project, he had more than a few joints to run through for the crowd. Watch him work the beat machine and rock the mic below, along with a stand alone performance of "Passing Fancies." Look for Jonwayne's LP, Rap Album 1, to drop later this year (dude consistently has the best album titles).
