Everyone's pretty much summed it up pretty well. American Beauty and Workingman's Dead are great albums, but I agree the live stuff is where it's at and there's plenty of it: Europe '72, Veneta OR 8/27/72 (The Complete Sunshine Daydream Concert), Wake Up to Find Out..., Spring 1990:So Glad You Made It, Cornell 5/8/77, I could go on and on. You start going down the rabbit hole and it goes pretty deep. And then there's Jerry's solo stuff! Unfortunately, I didn't get into the Dead and Jerry until after he passed. I sure wish I saw it live.
