Every year I stumble upon a new downtempo, chillout band that rocks.
This year, I found Bitter:Sweet while shopping at Fred Segal's in LA. Their 2006 classic (Mating Game) was playing in the store (and on sale for way to much money), so I went home a sampled a track via iTunes (Don't Forget To Breath).
It was trip hop of the finest quality, right up there with Portishead, Sneaker Pimps and Morcheeba. I don't know how I haven't heard of this electronic duo, but they are the freshest sound in this genre since De Phazz.
