I picked up the Tron Legacy soundtrack on iTunes yesterday, and it is wonderful. Thomas Bangalter and Guy-Manuel de Homem-Christo, AKA "Daft Punk" deliver some of their signature grooves, but also brilliantly mimic some of the best recent film scores from Hans Zimmer, Harry Gregson Williams, John Powell, Christophe Beck, and others (ostensibly with their help -- those composers are thanked for their generosity in the booklet.) You remember the big crunch-chord in the Inception soundtrack? I think Daft Punk lifted the exact orchestral voicings from Zimmer's score to incorporate that texture into the Tron Legacy soundtrack. Whether it is tribute with permission or plagiarism with a plea for forgiveness, I do not care. IT WORKS.
But the point of this post is to let you know that while iTunes has a couple of cool bonus tracks, Amazon has an exclusive bonus track on their MP3 version of the Tron Legacy Soundtrack that I had to pick up as well. I'm not sure of the cheapest (legal) way to get all 25 tracks, but #23 on Amazon, "Sea of Simulation," is delightful and exclusive to Amazon. It looks like right now you can get the original 22 tracks, plus "Sea of Simulation" for $7.99 via Amazon, and the iTunes store will let you grab the remaining two bonus tracks ("Father and Son," and "Outlands, Pt II") piecemeal for $0.99 each.
(Yes, I'll be seeing Tron Legacy opening morning. But that's next week. Tomorrow I think I'm going back in the closet for another trip to Narnia.)
