...unofficially. I can't distribute the tracks, though, they're not licensed.
(Check out Duffy's Neo-soul retro sound here: http://www.iamduffy.com - beautiful stuff. Her voice is a bit like Dusty Springfield's.)
I'll try to get the sax tracks separated out from her music and post them, but I doubt they'll sound the same without the rest of the music, especially the percussion.
I'd love to find a local band of beginners, or even some beginners online to collaborate with. Audacity makes it possible, projects can be zipped and e-mailed, then new tracks added.
Audacity can be found here: http://audacity.sourceforge.net/
This is a full-featured, 100% FREE, multi-track audio editor. Tracks can be exported as .wav or .mp3 .
The LAME MP3 encoder package and effects package have to be installed separately, but are fully integrated into Audacity once the installations are complete. All the download links and instructions can be found on the Audacity page.
