If you haven't seen this yet, go to Wolfgang's Vault. There are hours and hours of classic concert audio collected by the late Bill Graham that you can listen to for free (at least until they shut it down or start making us pay for it). They also have memorabilia and such but the concerts are great. I am listening to a Muddy Waters show from 1966 at the Filmore in S.F. as I type this. AWESOME.
Also listened to a Jimi Hendrix show from 1969 before I started on Muddy.
Check it out. I think you'll like it.
