UPDATED (November 10 2015):
K-Def recently shot an episode of Mass Appeal's Rhythm Roulette at Iris Records in Jersey City! Not only did he use all 3 records he selected, but he made one of the best beats in the whole series, in record time. Stay tuned as the episode is expected to hit the net in December. We'll post the ep here when it's live.
Much more than we can summarize here. K-Def has 3 + albums dropping over the next couple months. Check out this lengthy this post for previews of K-Def's upcoming projects with 45 King, Damu, El Da Sensei, & Much More. Post includes lots of links and audio!
