Amazon.comThe 126 a cappella voices heard on this 1991 field recording are not actually from Tahiti but from the island of Rapa (a.k.a. Oparo), a thousand miles southeast from Tahiti, the last outcropping of land in the South Pacific before Antarctica. The island's very isolation has allowed it to preserve a unique choral tradition based on quarter-tone harmonies, three-against-two rhythms, tenor-against-alto counterpoint, soprano trilling and bass-voice drones, and percussive exhalations. All 15 selections on this album date back to the days before the island's first encounter with Europeans in 1791 and have a distinctly non-Western character. The music's eerie strangeness is combined with an unmistakable beauty that made this album a surprise hit on the worldbeat charts. --Geoffrey Himes
