Electronic composition is probably some of the most progressive stuff out there right now - in any genre of music. I love Jazz, but a lot of new jazz is pretty stale. And modern classical compositions are often painfully contrived sounding. Electronic composers like many of the ones mentioned above, in contrast to DJ's - who often play music that sounds like it came out of a cracker jack box, (ie. uninspired repetitive generic), are creating some really interesting sounds and arrangements using purely electronic means or electronically manipulated samples. Faultline, Orbital, E*vax, Solvent, Hessen, Krueder & Dorfmeister, Underworld, Nils Petter Molvaer, Air, Radiohead, Beck, Nortec Collective, Couch, Silo, Arovane, to name a few. And also some of the pioneers of electronica mentioned above like Kraftwerk, Yello - 'Flag' is also a great one.
