...until they lost their original vocalist, Skye Edwards. She has an amazing voice. I actually think the world of electronica, and in particular trip-hop, has given us some gorgeous female vocals. Favorites of mine, off the top of my head, are: Beth Gibbons from Portishead, Liz Fraser from Cocteau Twins, and Sia Furler from her work with Zero 7. The trip-hop genre is practically a breeding ground for breathy, pop, chanteuses.
