73 . . . and quickly rising as the Zappa Family Trust start releasing more things from the vault.
So far, there's been a concert from Australia in '76, a compilation of early Mothers demos, & a newly released rehersal tape from the Petite Wazoo band in '72. Oh, and the just released QuAUDIOPHILIa DVD-A with old multichannel mixes Frank made (including the full studio Wakka/Jawaka

).
It's starting to get much more fun to be a Zappa fan. I think the total count is near 80 now . . . Good God.
More promised fetish items include a DVD of the Roxy concerts from '75 (Roxy & Elsewhere), Lost Episodes II, an eventual Petite Wazoo concert, some new remasters done by Dweezil & plenty more material from the vault (their old swimming pool Frank covered over).
