After winning an Oscar for Best Original Score for The Social Network, Trent Reznor and Atticus Ross re-team for the soundtrack of David Fincher's American adaptation of The Girl with the Dragon Tattoo. Reznor's and Ross' recorded score clocks in at over three hours. Other than a strident cover of Led Zeppelin's “Immigrant Song,” the score is moody, often restrained, and in its way, as disturbing as the film.
