I got into Pearl Jam back in 95. They actually helped me get into Zeppelin.
I love the progression of the band through the years. In my opinion they have gotten stronger each tour since 1998. They were so good in 05/06 it was almost hard to believe. They are on right now and I look forward to seeing where they take it over the next couple of years. Bonnaroo, here we come!
Check out some of that progression:

This is all legal. Pearl Jam allows tapers and has made it clear that streaming there shows is good by them.
