The Execrable Bede
An excellent introduction to the intoxicating and highly addictive Afro-Colombian marimba-based music of the Pacific coast. If you are looking for more Afro-Colombian marimba, check out the 2005 Grupo Naidy album "Arriba Suena Marimba" [Folkways/Smithsonian] as well as Nidia Góngora (with Quantic)'s 2013 EP "Muevelo Negro / Nanguita", available on Bandcamp.
Favorite track: Aguacerito.
