Thanks, Art and Rusty!
I believe the original SIN album is available on iTunes. As for a CD, I don't know if it was ever issued on CD but I'll ask at the next rehearsal. I'm sure there's original vinyl floating around the various used record shops here in MD, though that doesn't do you much good.
I too hope we can play TX someday. It looks like Ohio is the closest we'll get for a while. ;-(
Btw, as you'll see on iTunes, CTS has been releasing CDs pretty regularly. The latest is called Machine and has some very strong material on it. There's also a live DVD out from 2008 which is very good as well.
Cheers,
