It's the first ACL show from 1989 -- where her hair is blonde and she's playing with the original band. Gurf Morlix on guitar.
Thanks, @stuartk . I would have loved to seen her back then. As I typed previously, it wasn't until sometime after SOW I discovered her. Actually, it was because of her vocal work on Terry Allen's Human Remains (specifically it was the track Room To Room that I first heard off of that) that started my obsession. But back then I was too stupid to check the credits and see whose voice that was. So it wasn't until I bought Steve Earle/I Feel Alright that I made the connection. And then I bought every Lucinda CD I could find, which were far and few between back then.
So I didn't get her "White Album" until it was reissued and released the same time as Car Wheels.
