Who composed the Oscar-winning score for The Social Network with Atticus Ross?

Trent Reznor composed the Oscar-winning score for The Social Network with Atticus Ross.

Reznor, best known as the frontman and creative force of Nine Inch Nails, collaborated with Ross on an electronic score that gives Fincher's film its cold, tense, and introspective atmosphere. Their music contrasts digital innovation with emotional isolation, using synthesizers, ambient textures, piano, and heavily processed sounds.

The score was released on September 28, 2010, through Reznor's The Null Corporation label. Its standout pieces include the opening track "Hand Covers Bruise" and the reworked Ghosts material heard elsewhere on the album.

Reznor and Ross won the Academy Award for Best Original Score at the 83rd Academy Awards, as well as the Golden Globe in the same category. A frequent mistake is to name Jonny Greenwood or Hans Zimmer, but neither composed this film's score. Ross was Reznor's co-composer, so the complete credit is Trent Reznor and Atticus Ross.
