I've been able to find the standalone CD of Eldorado for preorder on several sites but not Time Fades Away.
Yeah, it was released in 2017 as part of this foursome: Tuscaloosa pairs-up nicely with Time Fades Away... Kenny Buttrey plays drums on Tuscaloosa and John Barbatta is on Time Fades Away, recorded later in the tour, but they sound great together.
Did they ever release the remaster of Live Rust that was in one of the Original Release Series boxes separately?
