Orchestra Gold (OG) celebrates the musical crossroads between Mali and the US. It’s where rowdy, psychedelic rock meets the analog tape sounds of W. Africa. Leading the train is electric front woman Mariam Diakite. The raucous sound of her vocals transport you to a street ceremony on a Sunday in Bamako. Their latest album “the Old & the New” draws deeply upon the canon of Malian tradition. But, it goes beyond that, forging a path into American rock and psychedelia, Afrobeat and Funk. OG is for the lovers of fat horns, heavy swinging rhythm sections, and spaced-out psychedelic guitar lines.
