Surfer Blood guitarist Thomas Fekete was diagnosed with cancer earlier this year, and the music community has rallied around him, but the road hasn’t been easy. After several benefit concerts back in May, some of the donations ended up being stolen in a van break-in. Fekete has had a GoFundMe page set up since he was diagnosed, and now musicians are releasing exclusive tracks in an effort to encourage more people to donate.

Yo La Tengo, Guided By Voices, Real Estate, the Pains Of Being Pure At Heart, Lou Barlow, and more are all contributing previously unreleased songs for the cause. Joyful Noise Records pressed one copy of each of the songs to vinyl, and each one is up for auction on eBay with all proceeds going to Fekete’s treatment. If you donate $10 or more via GoFundMe, you’ll get all of the tracks digitally.

Here’s a breakdown of the tracks available:
