Congratulations! You made it to the final installment in this series of three very special Zappacast episodes where Scott Parker tries to solve the mystery of Frank Zappa's greatest unreleased masterpiece: The History and Collected Improvisations of The Mothers Of Invention. Scott is joined once again by producer Phil Surkis, and Joe "Vaultmeister" Travers. Together, they try to summon their superpowers to determine what this infamous unreleased Frank Zappa box was, and can it ever be put back together. They know it was initially planned for release as a 12 LP box in 1969. When it didn't come out,  FZ kept hope alive in interviews throughout the years for a possible release of a version of this set.A few years ago, a document was discovered (and subsequently shared on the internet) of FZ's intended sequence of songs for a 9 LP version of this box, to be released in 1972.  With this invaluable information in hand, the Zappacast crew forensically examine volume one of the three volume 9 LP set.This episode focuses on volume 3 of the 9LP set titled, Things That Never Escaped From The Studio (And Elsewhere).Can FZ's unreleased masterwork be pieced back together? What has already been released? What HASN'T been released, but still may be lurking in the vault?  We think this is most exciting episode in the series!For all things FZ, visit The Official Frank Zappa website.Keep the conversation going on Twitter and Instagram.ZappaCast is:Created & Hosted by Scott ParkerSpecial thanks to Joe "Vaultmeister" TraversProduced by Phil SurkisContact ZappaCast: moi1969@snet.netDON'T FORGET TO REGISTER TO VOTE!
