the premiere date for tankian and sater's "prometheus bound" at the american repertory theater is february 25, 2011. the singer has said that collaborating on the show has been a great learning experience for him. "i’ve been using a lot of my archives, a lot of different types of music that i had already put together for underscoring and what not," he said. "it’s quite diverse, from noise to jazz to electronic stuff to hip-hop songs to rock songs to cool, piano dark underscores, and that’s a whole different bag of tricks there because it’s always evolving. unlike a film score that’s very linear and you get a scene to score for, this is something where you do another workshop and one song is gone, that underscore changes to 20 seconds and they need something else on the spot. everything’s always changing until the show comes, so it’s quite interesting."
