Trent Reznor and Atticus Ross' track "Hand Covers Bruise" from David Fincher's The Social Network is easily the most haunting and memorable piece of music from a film this year if you're asking me. That piece gently brings out the unbridled ambition and lurking isolation of its subject so profoundly - it fits the film like a glove.
So naturally I perked up when I listened to Fincher's commentary on the Social Network Blu-ray when he discussed the various musical choices that were in place before the final decision on the Trent Reznor track. Fincher had in mind Elvis Costello's "Beyond Belief" for the opening sequence while Aaron Sorkin wanted to go in a completely different direction.
Immediately, I thought, "oh, the opening sequence with the dubbed alternate musical choices will be on Youtube in a few days ." And low and behold, /Film and their readers have taken the initiative to splice the new songs in there. Of course, it's not really fair to keep the visual sequence the same with a completely different audio track, but you get the general idea.
So here is the Aaron Sorkin version with Paul Young's "Love of the Common People". Needless to say, thank you, Trent Reznor.
As of right now, I don't think the Fincher/Elvis Costello version has been uploaded by anybody yet, but I'll try and post it as soon as I can.
