An official bootleg I'm very happy to own on CD. my favourite band of all time, and their energy in shows is beautiful always, but something about this recording is completely unmatched. It's probably my favourite live album ever. Their back-to-back sets Alivelectric and Aliveacoustic are also very good.
Also quite partial to STRFKR's Live from Brooklyn Steel, and Les Rallizes Dénudés only has live albums, but '77 LIVE is a great psych noise rock show. It just now occurred to me that you might be talking about concerts specifically and not just live albums, so I'll also throw in that I saw They Might Be Giants in Ithaca, NY for their Flood 30th anniversary tour and it was a real delight. They pull out so many tricks that I was just wowed by!
