As to the selection...this is a tuff one. I am going with The Who, just because of nostalgia.
I'm quite familiar with the CNSY album as well, and it's nothing to sneeze at.
However; when I hear "Yong Man Blues" it always takes me back to listening to the crappy MCA record on a record player that had one speaker. The intensity of the song cemented my devotion to rock and roll. There is a pure abandon in that performance that I really love.
