There'll be a mix of genres and instrumentation, in the hopes of providing each level with a unique feel. The less intense moments, such as the action or the calm before the storm, won't be particularly "classical" or orchestral. The last thing I'd want is the music taking you out of the moment and completely clashing with the gameplay (-and I'm not talking about the lovely Baroque music vs modern violence juxtaposition as in the Bach piece in the original trailer), but we also want more depth than interchangeable DnB combat tracks in each level.
