Peter: How about considering some Django guitar backup tracks for the following styles:
j_django.sty, j_djang2.sty, d!~htclb and j!~club
The midi really sounds great on my Yamaha SW1000 sound card but I can imagine what Real Tracks would sound like! John Jorgenson would be the artist you need to lay down the tracks. Simply one of the best there is now.
Thanks
