As far as I can tell, it's one site now and it works like this: Wolfgang's Vault is now "Wolfgang's" that handles memorabilia and 'stuff', and Concert Vault is now "AMP'd" which handles the concert audio. They're both included in one subscription of $40/year. Considering the amount of historic music available, that seems like a good deal to me. On the other hand, I think that price is for streaming only - downloads cost an additional $5 each.
