The Afro Celt Sound System is a musical group which fuses modern electronic dance rhythms (trip-hop, techno, etc.) with traditional Irish (Celtic) and West African music. It was formed by Grammy-nominated producer-guitarist Simon Emmerson, and is considered to be something of a world music supergroup, often featuring a wide range of guest artists on their albums. Their albums have been released through Peter Gabriel's Real World Records, and they have been cited as the second best-selling band on the label, exceeded in sales only by Gabriel himself. Their striking live performances have often been the highlights of the WOMAD concert festivals. They signed a contract with Real World for five albums, of which the 2005 release Anatomic was the last. After a number of festival dates in 2007, the band went on hiatus. In 2010, they regrouped to play a number of shows (including a return to WOMAD ) and announced a new album, Capture.
