I love watching old performance videos of bands right before they hit it big.  My favorite I posted a while back was a Rage Against the Machine concert on a college campus with about 10 people actually paying attention and the rest of the people just rushing by on their way to class.  This video I found of Linkin Park is pretty great too.  This is Linkin Park playing a little club show in the summer of 2000 just months before their Hybrid Theory album dropped and made them a huge success..........
