Not really a Deadhead but I do have the debut----brilliant album, and in a way so unlike anything else they ever did.
I love the first three LP sides of Live/Dead, particularly now that they segue together on CD.
The other of theirs that knocks me out is the kaleidoscopic (and extraordinary) Anthem of the Sun.
I also like the first three GD albums. Especially their debut. Not too crazy about the rest of their catalog though. Although American Beauty has a couple good tunes on it. Sugar Magnolia is a great song.
