Back in 1995 Jamiroquai and Guru (one half of the hip-hop act Gang Starr) collaborated on a track called "Lost Souls" - which was featured on one of Guru's "Jazzmatazz" compilation albums.
EMI/Virgin have just announced a new album entitled "The Best of Guru's Jazzmatazz" and the Jamiroquai/Guru track has been selected for this compilation."Guru's vision for Jazzmatazz respects and reveals similarities and complementary elements between hip-hop and jazz. Both genres' focus on rhythm and improvisation, coupled with Guru's balanced and fluid approach to his musical blends, have eased the way for artists to come together and participate in an entirely new musical experience within the creative realm of Jazzmatazz."
More information and the tracklist for "The best Of Guru's Jazzmatazz" album is given in the official press release.
