Klaus Schulze/Lisa Gerrard - Farscape (2007)

This is a fantastic collaboration between the legendary electronic composer (formerly of Tangerine Dream fame) and one my all-time favorite female vocalists. As Allmusic notes, it is quite repetitive, but that ends bringing a hypnotic quality to the soundscapes. One minor criticism is that the two musicians' styles seem to clash at certain points, but for the most part they complement each other beautifully.
