For centuries, a remote village in the southern Rif mountains of Morocco has been home to the ecstatic trance rituals of the Master Musicians of Jajouka. And for decades their hallucinatory jams, performed on hand percussion and pipes, have acted as a beacon to some of the West's more adventurous artists and musicians. William Burroughs visited in the 1950s; Brian Jones recorded an LP's worth of music in 1968; and Ornette Coleman jammed with them for his 1974 album Dancing In Your Head. Indeed, the most successful of this batch of remixes and new collaborations finds Ornette revisiting the same tactic he used then: weaving his weeping alto among the keening, cyclical improvisations of the Jajouka pipes. Sadly, the rest of the tracks are less convincing: Medeski, Martin & Wood obliterate kif-drenched atmospherics with a funky backbeat; John Zorn adds scalding sax to a heavy breakbeat that can't summon even a fraction of the original's transporting delirium; and drummer/producer Billy Martin oversees an airbrushed dub reggae remix. Proceeds of this benefit album will return to the source at The Jajouka Foundation – but sadly even that's probably not a good enough reason to buy it.
