Re: Saxophone concertos
If anyone is still actually checking this posting, here are a few more good pieces.
Concert Suite - William Bolcom (sax and band or piano, very hard, lots of altissimo..but very fun too)
Sonata - David Diamond (sax/piano) challenging, but has some osia passages that make it easier if you aren't up to speed on your altissimo
Distances Within Me- John Anthony Lennon (sax/piano) also very hard, unmetered in places and very rhythmicly complex. Awesome piece.
Interplay - Charles Ruggiero (sop./piano) Hard as hell, not for anyone but the most serious players. Very cool piece, very jazzy, but the fastest thing I've layed eyes on. Starts about quarter=240.
Much of the newer literature is "out there" so be prepared. Some of it is very good, but some is just hard and weird.
Oh yeah, one more....
Duo 1.5 by Jerry Grant. (alto/tape) This is not your typical tape piece. It is very lush and orchestral sounding. The sax part is demanding, but not overly so. Very cool piece.
