You MIGHT be able to find some Gordon & Kottke (Gordon comes first, he has the name recognition) on furthernet or etree. I'm not too sure, I use bit torrent almost exclusively now-its much, much faster.
I have eight shows of theirs (seven from 11/02, one from Bonnaroo '03, which is decidedly inferior) and can do B&P (blanks and postage) for any circle members who are interested. Drop me a PM.
I have a couple solo Leo shows as well.
I saw Leo Kottke perform in August or September, and he mentioned that he and Gordon are getting back together to make another album.
