Without having yet seen the list, the ones that come to my mind are....
the Led Zeppelin DVD. About 6 (or maybe more) hours of prime footage from throughout their career. But it might not count because it's not a 'movie.' (Does it even have an official title? I've only heard it referred to as the Led Zeppelin DVD.)
The Kids Are Alright -- again, not one concert, but many Who performances over their career.
Woodstock
-- obvious choices.
Monterey Pop
Gimme Shelter -- the darkest and most disturbing of all concert films. But a great document.
Queen -- I don't even know the name of this was, but PBS showed it about a month ago and it was Queen playing in Toronto, and it looked like mid-80s. I wasn't aware it existed until I saw it, and it was great.
The Song Remains the Same -- for many years, this was the only video document of Led Zeppelin in concert, and it has a certain amount of magic. But when I bought this VCR tape in 1988 and eagerly popped it in, it occurred to me early on that something wasn't right with Plant's voice. By '73, his voice had already cracked, and he couldn't hit the high notes from the early albums. But Page and the bow were awesome. Thank god for the Zeppelin DVD.
I might be forgetting a few, and I'm sure there are a number I haven't seen, but those are the ones that come to mind.
