The concert of your choice.

[El Bandito]

Either Queen in their prime or The Clash in their prime.

Seeing Hendrix live would also be amazing.

[Bunny]

Beethoven. Circa whatever year he was active.

[Devourment]

I'd probably go see Led Zeppelin dominate somewhat early in their career. Small venue. Yeah.

Either that or Jimi Hendrix / Black Sabbath.

[Resha]

I'd kinda like to do Woodstock '69. Just to feeel the feel. I would've quite liked Band Aid '85, too. These two really big musical glitches in time.

All my energies are currently directed at finding Dylan in my vicinity though

[Proxy]

Yeah Zepplin would be a grand choice.
However, I'm pissed that I missed the Taste of Chaos tour in Toronto 2 or 3 weeks ago. I would have really liked to have gone to that.
But, Billy Talent & AoF coming up soon! =D

[Odaisé Gaelach]

It would probably be Live Eight.

Nah, scratch that. I'd be on the rooftop with The Beatles.

[Necronopticous]

The Beatles, of course. Right after December of 1965.
