Sadly I only found out about the Vault by reading a newspaper article about the laws suit launched by Grateful Dead Productions, Carlos Santana and members of Led Zep and the Doors.
Personally I think it's bloody brilliant that anyone can listen to this stuff for free and it's a shame these artists can't see the site has the potential to sell more records for them by exposing more people to their music. Then there's all us old farts who already bought the artists vinyl records, then their CDs!
Good luck Mr Sagan, I hope you can work something out to keep the site going.
