This is very good news. For those of you who do not know, Wolfgang is Bill Graham, who was responsible for promoting a large amount of classic shows in the 60's-80's.
Mandatory reading for any serious rock fan. I keeps mine on the back of the toilet ;)

The Android app that came out for Wolfgang's Vault is awesome too not just his incredible concert archive but also Daytrotter Sessions, SXSW, Newport Folk, etc.. Free too.
