Moloko - I Am Not a Doctor (1998)
Moloko (producer Mark Brydon and Róisín Murphy, both from Sheffield) come from the "broken beat" genre, which is essentially the bastard child of trip hop, drum and bass and techno and often creates an almost IDM-esque atmosphere in terms of quirkiness and musical unorthodoxy.
I Am Not a Doctor, the band's second out of four studio albums, is steeped in both energetic funky house music, as well as more lethargic, groove-based trip-hop a la Massive Attack. This creates an interesting and fairly distinct set of sounds which is both artfully unconventional but also sounds like it was a hell of a lotta fun to make.
