Thriller planning: Soundtrack

One of our initial ideas for the soundtrack of our thriller is from Sergei Prokofiev's ballet 'Romeo and Juliet', the specific track being 'Montagues and Capulets'. We like this piece because its very powerful and sinister, and would fit in well with a theme of betrayal and deception. This soundtrack, being a classical piece, would give our thriller a more classic style.

Another idea for our soundtrack was to have something more modern, that isn't a classical piece, and that is dark and industrial. Something similar perhaps to the soundtrack from the opening sequence of Sin City, or perhaps something like an instrumental version of something by Marylin Manson. Should we choose to go with a piece like this, our thriller would definitely have a more modern style.
