With its earliest example a duet between Peter Tosh and Mick Jagger from 1978, this two-hour, 24-track compilation pitches a wide variety of collaborations between world music artists and colleagues from Britain and America. On the one hand, we find the likes of Youssou N'Dour, Femi Kuti, King Sunny Ade, Angelique Kidjo, Baaba Maal and Tito Puente; on the other, Gorillaz, Wyclef Jean, Ry Cooder, Eric B & Rakim, Nitin Sawhney and John McLaughlin. An adeptly managed project which works surprisingly well.
