Specials below are from Wolfgang's Vault. Wolfgang was Bill Graham. Born Wolfgang Grajonca in Berlin in 1931, he escaped Nazi Germany to grow up in a foster home in the Bronx and anglicized his name at the age of 18.  The vast majority of material in Wolfgang's Vault comes from the exquisitely preserved, original archives of Bill Graham Presents. Beginning with the seminal concerts of the mid 1960s and continuing through today, it is a a superb collection.
