The Avett Brothers bassist Bob Crawford raises awareness for brain tumors in the first-ever public service announcement (PSA) in support of brain tumor research.

Crawford’s daughter Hallie was diagnosed with a brain tumor in August of 2011. Since then, Crawford has been outspoken about his family’s struggle and the struggles of 700,000 Americans living with brain tumors today.

The PSA, sponsored by the National Brain Tumor Society, highlights the need for funding for medical research in addition to the musician’s own story.
