Disturbed frontman David Draiman is working on a new autobiography, in which he'll chronicle his upbringing in Israel and his Jewish beliefs.
The heavy rocker, who once considered becoming a rabbi, has announced he's three chapters into the tome via a post on Twitter.com.
Draiman and his bandmates are currently on an open-ended hiatus, which the singer announced last year (11).
At the time he said, "We've got other things that each of the band members wanted to pursue individually, outside of Disturbed. There's other businesses we have, there's other interests."
