“Question: these soundtracks, like the ones in Trine and SSHD, seem to be complete tracks that run from start to finish in a game-level. Have you thought anything about music that shifts intensity and tempo depending on the gameplay? Having changed soundscapes, loops inside the song, bridges determined by game-events.. that kind of thing? (..like, Riff: everyday shooter, or maybe Motoi Sakuraba’s soundtrack in Resonance of Fate, pixeljunk Shooter to some extent)..? How difficult is this to do together with a developer – do you need more involvement in the development process.. that kind of thing?”

Eh I think you need to read the interview, Mr. Pulkkinen states that the music is dynamic and that it adjusts in tempo and intensity to suit the gameplay.
