Sitting here at work, I'm listening to some chill/downtempo stuff similar in "feel" to Chicane (chill, ambient, beats, trippy). Here's some recommendations to check out.
~The Dining Rooms (two guys out of Italy, very chill with trippy.beats.cafe.style stuff)
~Thievery Corporation (two guys out of Washington DC, anything they touch is usually gold... required downtempo)
~Tosca (group like Thievery Corp, good stuff)
~Kruder & Dorfmeister (two guys out of the UK, very similar to Thievery Corp)
~Bonobo (he's an artist out of the UK), record label is Ninja Tune
~Shpongle (two guys from the UK, a little abstract.beats.trippy.funky.weird.stuff, very cool if you open your mind a little bit)
~Hotel Costes Series, set of CDs, I think they're up to Volume 7 or 8?
~Cafe del Mar, set of CDs, again I think they're up to Volume 10 or 11?
