Wolfgang's Vault

If, like me, you happen to be a fan of 70's music (Dylan, The Band, Joni Mitchell, Van Morrison, Neil Young etc.) when you discover Wolfgang's Vault you will feel like you've been locked in the proverbial sweet shop. It is the most amazing collection of live recordings - mostly from that era - imaginable.
The story goes that legendary concert promoter Bill Graham, (definitely not to be confused with Billy Graham!) made live recordings off the mixing desk of many of the concerts at his venues (such as the Filmore East in New York, the Filmore West and Winterland (venue of the Last Waltz) in San Francisco, all in all some of the most important concerts in rock history).
After a long legal wrangle over the rights of these recordings they are now available to stream for free from a very high quality site. It's called Wolfgang's Vault because Bill Graham's original name was Wolfgang Grajonca.
Anyway, I've just listened to an amazing Van Morrison set from New York in 1978 while I've been working this afternoon. Get on over there and register for free if you too feel like someone born at the wrong time!
