Previously mentioned Coin Locker Kid has one of the most unorthodox approaches to hip hop that I've heard in the past few years. I didn't love the last full-length I heard from him, but I still left puzzled by his odd rhymes, stories, and instrumentals.
There's a clear hip hop influence running throughout his music, but electronic and experimental music guide a lot of the compositions on this new project as well. The title of this thing: Traumnovelle. It's available now via Already Dead Tapes, and you can purchase this album via cassette here.
