I haven't seen these, but I ran across them yesterday while surfing and I've added them to my gotta-have list:
Lucinda Williams on Austin City Limits. This is from the
Car Wheels on a Gravel Road tour -- I caught two of the shows on this tour, and she's in peak form. Scheduled for release May 10th.
Townes Van Zandt -- take a minute to read the description of this one. Wow, wow, wow, wow. I want it right this minute.
Richard Thompson on Austin City Limits. Also scheduled for release on May 10th. Looks like they're gearing up for a long list of ACL releases.
