Richard Rodney Bennet wrote two sax concerti, a quartet, a sonata for soprano&piano, and a short set of 3 pieces for alto and piano.
If you wanna wait a bit John Corigliano is apparently working on a saxophone concerto, according to an NPR interview recently.
Also Benjamin Britten authorized people playing his 6 Metamorphoses after Ovid on Soprano sax.
(+1 on Odsum and John's reccomendations (although like he said, probably looking for classical stuff given subforum this is in), and for Blue Dog's mentioning Tipton, as I've never heard of him before now.)

Wow, that's excellent news. I really like his Red Violin score and the Chaconne and then full Violin Concerto that he derived from it. Plus, it never hurts to have a "name" composer write for the sax.

Considering the small amount of what I've heard of his music, I'm definitely interested to hear it!
