yoko kanno is the wrighter (<-- why does that word look wierd?).
I also believe "the seatbelts" are the performers
you might check out Miles Davis as he was something of a bebop pioneer (AFAIK). (also known for hard bop, cooljazz, fusion, funk, etc)
other good names (may or may not be to your liking):
Wynton Marsalis (more classical though)
Branford Marsalis (more abstract though)
Dizzy Gillespe -- pioneer
Thelonious Monk -- pioneer
George Clinton
Sonny Collins
John Coltrane <-- aside from Mile Davis's "Kind of Blue" album, this guy is the best "bed music". (IMHO)
Good Link
