Then, Bunky, have I got a Website for you! It's called Wolfgang's Vault and features streaming and downloadable concerts from nearly everybody you like. The Basic access is free; Paid (WVIP) gets you other stuff and higher quality audio. Streaming free in Standard Mode works for me. Great thing: find a concert and it plays the whole thing. Also available is merch from back in the day--posters, t-shirts, unused tickets, etc., etc.
Here's the Site:

Bonnie Raitt:

BTW, if you're full-on freaky-deaky music geeky like me, know they cover all genres.
