Music from Gabon can be hard to come by outside of the Central African country’s borders, and even in Gabon, it’s been tough to track down Papé Nziengui’s late ‘80s, postmodern masterpiece. Kadi Yombo is Gabonese harp music, which is mostly played in sacred Tshogo rituals, mixed with synthesizers, a male voice and female chorus in response and percussion at a blistering pace. Long out of rotation at home and abroad, the crate-digging label Awesome Tapes From Africa is reissuing the album April 8, and has just released the first single from what will be a double LP.
