Featuring music composed by Brian Tyler, the soundtrack consisted of 20 tracks which was released by Lionsgate Records on August 10, 2010.

Composer Brian Tyler announced on his official website that he had been hired to write original music for the film; he previously worked with Stallone on Rambo (2008).

The score album was announced in mid-July 2010 and eventually distributed through Lionsgate's music label on August 10, three days before the film's release.

"[6] Peter Debruge of Variety wrote "Brian Tyler’s temp-sounding score beats its drums and blows its horns".

Erna showed him a potential unfinished piece of "Sinners Prayer" originally recorded for his debut album Avalon (2010);[8] Stallone liked it and wanted to use it in the film.
