I found this album through a co-worker a few weeks ago. It's really quite good. The "Soul Mates Project" has a few other albums that are worth checking out if you like this as well.
If you're curious what this is about, here's a description from that site.
Amerigo Gazaway’s *Soul Mates* series continues the theme of his previous work in creating collaborations that never were. On the series’ latest installment, Amerigo unites Brooklyn rapper Yasiin Bey (Mos Def) and soul legend Marvin Gaye for a dream collaboration aptly titled “Yasiin Gaye”. Building the album's foundation from deconstructed samples of Gaye’s Motown classics, Gazaway re-purposes the instrumentation into new productions within a similar framework. Carefully weaving Bey’s tangled raps and Gaye’s soulful vocals over his new arrangements, the producer delivers a quality much closer to an authentic collaboration than a lukewarm "mashup" album.
