Petri’s been working on a movie score since June 2011. The movie is based on a script by Stobe Harju (who’s also directing the film) and Mikko Rautalahti, and is based on a yet unreleased album by Nightwish, under a work title “Imaginarium”.

What’s really interesting is the fact that Petri’s using Nightwish’s raw album multitrack data as his building blocks, taking sound design and audio manipulation onto a totally another level using methods and a toolset one would normally employ for a scifi movie. According to Petri, he’s trying his best to keep the score “as acoustic as possible”, even though some sections and instrument groups are definitely going to be mangled beyond recognition.

“It’s not going to be just a bunch of ‘remixes’ of Nightwish’s songs”, Petri adds, “instead, they’re rather a quite serious set of careful reinterpretations based on their brilliant songs and orchestrator Pip Williams’s magnificent work.” The movie premiere will be held in 2012.
