Smashing coconuts with Sufi group Sidi Goma | World | Guardian Unlimited Music
Nothing quite prepares you for the stunt that rounds off a typical show by Sidi Goma. The 12-piece Sufi group from Gujarat begin their ritualistic performance with a sedate a cappella azan (Muslim call to prayer), followed by hypnotic percussive workouts, with most of them sitting down as they play.

Sounds like this group is combining African and Arab musical elements.
