My favourite recent listen is a group called the Seatbelts out of Japan headed by composed Yoko Kanno. The band did a whole series of albums for the Cowboy Bebop that is a Japanese anime series set in the year 2071 about a bunch of bounty hunters (cowboys) touring around in their ship the "Bebop". The music varies wildly from a 60's style horn jazz to modern acid jazz to straight on blues and what have you.

Give a listen to this Seatbelts mix
