Ok, do you want specific tracks or just artist names to check out? Let me know and I'll forward you specific tracks. For now, here are some artists that haven't been mentioned yet...

Morcheeba
Esthero
Mono
Sirenes
Hooverphonic

And yeah, Carter USM is great too, (IMO anyway!) but not trip-hop at all.

But my favourite album these days (recently anyway) is Wonderland by the Charlatans - no, not Trip-Hop. More like just rock, but some big beat and dancy grooves this time around.
