The Residents' album Eskimo. Available here on LP and CD.

The most rewarding, the most difficult, and the most accomplished of all the Residents' albums, this was their departure into the field of imaginary ethno-musicography that they had begun on "Six Things to a Cycle" onFingerprince. Ostensibly a musical documentary on the Eskimo, this is an album of icy atmospheres, poetic electronics, and imaginary landscapes, concocted around a loose narrative told in the liner notes. There's also a subtheme of indigenous populations overrun by western commercialism (is that native chant actually "Coca Cola is Life"?). Ex-Henry Cow member Chris Cutler plays a lot of the percussion on the album, especially on the finale, "Festival of Death," the only real piece of rhythmic music here, which shines out as anything but dark or sinister. In any other group's hands this would have been a pretentious disaster, but the Residents pull it off through spirit, humor, and sheer bravado.
