The soundtrack to Minority Media's Papo & Yo will be available tomorrow on the North American PlayStation Network. A price was not given in the announcement on the PlayStation Blog, but the soundtrack will be discounted by 15 percent off the regular price (30 percent off for PlayStation Plus subscribers) until Jan. 4, 2013.

The Papo & Yo soundtrack was composed by Brian D'Oliveira, who learned 15 new instruments in order to create the sounds required for the game. D'Oliveira also learned to play a few unconventional instruments, like a refrigerator. "When Monster runs, the sound effect actually comes from hitting a fridge," he says.

In addition to the soundtrack sale, buyers will be able to pick up a copy of Papo & Yo as part of the PlayStation Essentials deal and save 30 percent off the regular price of the game (50 percent off for PlayStation Plus subscribers). This deal runs from Dec. 24 to Dec. 30.
