Snubluck is a beatmaker from Denver, and is kind nice, he has quite a few releases on campband and soundcloud to listen to.

Anyway, this album isn't so much instrumental than remixes taken to that next level of beat-gen madness, "Remix Tape Vol.4" is kind of an acquired taste than some regular hip-hop or downtempo shit; you have to check it out for yourself, I like almost half of the tunes but the entire album is free to download so it's not like you have to pay for it, what you don't like you can delete.
