Clint Mansell does some very good work as well:

He's a guy that, clearly, put in his time studying music (formerly or not). So much of his work is reminiscent of mid/mature Arvo Pärt. Good shit.
For those not versed: Arvo Pärt was the progenitor of "tintinambulation" (the "rounding [tolling] of the bells") -- a musical process in which a repetitious [see "rounding" or "circumambulation"] motif that resembles the tolling of church bells (utilization of harmonic content and constant rhythmic repetition) is the primary theme that is augmented and diminuted throughout the composition. It's an extension of minimalism in a way, but with an eye further into the past to techniques such as idee fixe [see Berlioz, Symphonie Fantastique].
