Add equal parts Sun Ra, Fela Kuti, ’60s psychedelia, and Talking Heads’ Remain in Light-era poly-rhythmic Afrobeat, sprinkle a dash of ’70s disco with a chaser of Flaming Lips on-stage spectacle fun, then mix it one tall glass and you have the original sound of the Golden Dawn Arkestra. This is an intoxicating brew that’s best taken in doses long and slow, with a steady infectious beat.
