Yeah, what he said . . . New Orleans-style jazz, classical music played by New Orleans-based classical saxophone players, written music, recorded examples? If you mean real New orleans jazz from the original-jazz era, look for recordings by Sam Morgan's band, Papa Celestin's Tuxedo Orchestra, Jelly Roll Morton' Red Hot Peppers with Stomp Evans on alto, just for starters. Also Jimmie Noone's Apex Club Orchestra and Jabbo Smith's bands from 1929 used a lot of alto saxophone. DAVE
