The score for Donnie Darko is one that takes us into another realm, full of suburban surealism, and various ethereal overtones. The effect is intoxicating. I found myself listening to this soundtrack over and over again as I swung on the family glider in the backyard. I felt like I'd crossed over into another place, and no, I wasn't on anything! ;-)
Michael Andrews has elevated himself into becoming one of my favorite composers - and to think this was his first film score. His moody tone is deeply otherwordly and full of both anxiety and beauty. Many would compare this music to something along the lines of Danny Elfman's work for Tim Burton, and I'd have to say that I agree a bit. We hear simple piano melodies turn into stark choruses, then resound into joint blissfulness.
Take note, these songs do not hit the high emotional peak where you found yourself while listening to scores like Shawshank Redemption or Braveheart. This is more along the lines of Carter Burwell's Fargo, David Julyan's Memento or even the work Jeff Gibbs did for Fahrenheit 9/11. It's dark, dreamy, and would probably go best with a few sleeping pills.
* Not that you'll probably care, but I have over 120 movie soundtracks. Donnie Darko, even though I heard it four years too late, is one of my top 20. My only complaint is that many of the songs are only one minute long.
