Guilty Simpson and Madlib present OJ SimpsonThe slew of collaborative hip-hop releases this week is surely one the best in a long while. On one hand, you have the New York meets Jamaica via Africa eclecticism of Nas and Damian Marley's 'Distant Relatives.' On the other, Talib Kweli and Hi-Tek (under their Reflection Eternal moniker) have returned to drop 'Revolutions Per Minute,' a great mixture of soul, jazz and funk beats with Kweli going political and still rocking the party. But the real sleeper is Guilty Simpson and Madlib's 'OJ Simpson' collaboration.

Similar in spirit to beloved 2004 stoner classic 'Madvillainy,' Madlib handles production duties throughout with his typically ADD-ridden mash of bump and hiss. 24 tracks that bleed into each other over about 55 minutes, Detroit's Guilty Simpson rocks some playful gangster rhymes interspersed with Madlib's bizarre musical interludes, fake news segments and California medical dispensary-fueled sound collages.

Check 'Cali Hills,' a free MP3 from their label Stones Throw, to get a good handle on how the record works. It's a J Dilla tribute song that works like an odd encyclopedia of the prolific producer's interests and work over the years. You get a wispy Brazilian guitar melody over an ultra-compressed drum machine crunch, and even a self-referential sample of 'Baby' -- a track off Dilla's 'The Shining' that featured both Guilty Simpson and Madlib.

You can order 'OJ Simpson' from Stones Throw or purchase at your favorite online retailer.
