O'Donnel: http://www.youtube.com/watch?v=SRA3gdvUfpI Zimmer: http://www.youtube.com/watch?v=Z0kGAz6HYM8 O'Donnel did Halo up until Reach and Zimmer did MW2 and MW
It depends on the mood. Marty's music has HEAVY fonk. Zimmer is more serious and dramatic. Personally, Marty's music is more "beautiful" and speaks to me more because of its range. As in, if you don't find the thrashing Steve Vai guitar solos on the Halo 2 V2 soundtrack hilariously awesome because of how "irrelevant" they are, I don't think you're getting the full experience of the music. I mean come on, "Reclaimer" was put RIGHT before "High Charity Suite." When listening to the album in order, it's just one end of the spectrum to the other. Not just in terms of composition and instrumentation, and mood, but in attitude. Mary likes some tracks to "kick-ass" while Zimmer seems to like every track to be "heavy hitting" whether light or dark in tone.
