I really need to ask him something. We don't know. Your best bet is to write him a letter via Tzadik. Supposedly, it is a limited edition of 1000 copies. Word is that the release date has been pushed back to Fall 1997, my guess is that is optimistic.
More recent info seems to indicate that the project has been cancelled.
Masada is the name of an almost impenetrable mountain-fortress which was where a group of Jews stood against the Roman army in a very prolonged seige. The Romans finally defeated the rebels by using Jewish slaves to construct a ramp up to the main gate. Unwilling to kill thier own people, the Jews inside Masada could only watch as the slaves were forced to build the ramp higher and higher. Finally, instead of giving the Romans the pleasure of conquest, the Jews inside Masada defiantly commited mass suicide. I believe that this is generally considered the beginning of the Holocaust.
