Wolfgang’s Vault is run by William Sagan and houses a collection by the legendary concert promoter Bill Graham. Recordings include performances by The Rolling Stones, James Taylor, The Allman Brothers Band, The Grateful Dead, R.E.M., and many others. The Wall Street Journal once referred to the works as “the most important collection of rock memorabilia and recordings ever assembled.”After the lawsuit from many music publishers came, and the press announcement from its trade association was disseminated, a counterclaim for defamation was filed in New York federal court.
