From Dweezil Zappa World:
"P.S. The FZ ROXY audio is being assembled - tapes are being baked - so
that the process of synchronization can occur. The film negative was
transferred to Hi Def and the audio is captured at the highest
resolution from the original analog tapes. YES this is getting
underway... Had to get this one done to clear the way for the REAL ROXY."
