such a hard question to answer, U2 and The Police at Gateshead, The Rolling Stones at Hampden Park, AD/DC at The Apollo Glasgow, The Chemical Brothers at the O2 Glasgow, Cypress Hill at Tea In The Park and so, so many others.

Iron Maiden - Rock in Rio (2001)

Lenny Kravitz in Warsaw, Woodstock are also nice http://www.youtube.com/watch?v=GeV9x-Z35Jc

Alice in Chains unplugged was already posted, so it'll be Alice in Chains - Facelift Live for me. Just listen to this!

Gwar, Cradle of Filth, Tool, Pantera all have great shows (did, R.I.P. Dimebag)

Gary Numan is truly king of new wave!!!

I haven't been to many concerts sadly, I'm pretty tempted to go to a Grizzly Bear concert that's going to be right across the street from where I'm at now in March, though.

It's not really concert, but any music fans should check out LaBlogotheque, great channel of indie musicians of all types playing in the streets and public buildings, they've had a lot of well known indie bands (as if) too (Battles, Phoenix, Grizzly Bear, Fleet Foxes, J Tillman, Beirut, etc.). My all time faves are White Winter Hymnal by Fleet Foxes, and 1901 by Phoenix.
