Analog Africa is back with another of its eye-opening and mind-altering trips into musical wonderment here as the 20+ year-old label digs deep into the Andean city of Quito. It's the Ecuadorian capital and home to the music which makes up this vital collection and which owes so much to Polibio Mayorga. He spent much of his musical career trying to - and succeeding in - modernise the ancient rhythms of his region, namely Huaynito, Sanjuanito and Albazo. He did so with cutting-edge - at the time - electronic equipment and a trusty Moog and the result of his effort was that he is now regarded as a pioneer of tropical psychedelia. Dig in deep to hear how that happened across these superb 16 sounds.
