Grupo Chonta

Colombia boasts one of the world’s deeper marimba traditions in the currulao music of its southern Pacific coast. Hailing from Guapi, Diego Obregón rocks the Afro-Colombian marimba (a descendent of the West African balafon), which is usually accompanied by three (or more) percussionists playing the cununo drum and guasa shakers, though he was fronting a jazz group at a recent gig here. Either way, it’s polyrhythmic trance music with liberationist tendencies.
