If you had a time machine - could go to any year and set up a battle of the bands between 2 groups which would they be and when?Hoo, boy, but that's a loaded question, isn't it? I think what he's getting at is that you could pick Aerosmith from 1972 to go up against Limp Bizkit from 2004 as opposed to current-day Aerosmith, etc. Hell, putting 1978 Van Halen against 2012 Van Halen would be pretty damn interesting right there. Duke Ellington and his Orchestra from ~ 1940 vs. Mighty Mighty Bosstones circa 1999? Metallica 1984 vs. pretty much anything masquerading as current "heavy metal"?
What would your timeless matchup be?
That is all.
