Itās a really good album, but a stretch to call it the greatest in my opinion. It was an interesting one-off project, but Nirvana had far better live performances from the footage Iāve seen that were true to their sound. Lithium from Live at Reading, for example.
The greatest live album is Deep Purpleās Made in Japan, and take your pick of the tracks.
The best performance on an MTV unplugged record goes to AIC.
Would agree with all that with the caveat that Child in Tine is the greatest live performance of them all so obviously the best on the Live in Japan album.
