Christina Perri Contributes 'Tiny Victories' To HBO Documentary 'Foster'

Christina Perri has shared "Tiny Victories," a new track written for the upcoming HBO documentary about the foster care system, Foster.

"Tiny Victories" is about overcoming obstacles and celebrating those triumphs, no matter how small they may seem.

"It is an honor and a privilege to lend my voice and words to this story," Christina says in a statement. "The song is about overcoming something standing in your way, when sometimes it can look very small, but only you know how important the victory is."

She adds that both she and the song’s co-writer, AG, were pregnant when they wrote the song. Christina explains that that fact made the song even more poignant, because they were both experiencing new challenges and insecurities.

"‘Tiny Victories’ encompasses every truth we have and I hope it speaks to the subject matter of this powerful film – that triumph comes in all forms; it’s all meaningful, it’s all a victory," she concludes.

Foster premieres on HBO tonight at 8 p.m. ET.
