Mac DeMarco has put four test pressings of his 2012 EP Rock and Roll Night Club up for sale, and the money is going toward a worthy cause. Available on Discogs via Captured Tracks, the records are raising funds for people still reeling from Hurricane Maria in Puerto Rico. All proceeds from the test pressings will go toward the Caribbean hurricane relief initiative Waves for Water; Captured Tracks will also match the Discogs donation with $250 per record. Each pressing is unique, featuring different doodles and signatures by DeMarco himself. His message to Puerto Rico: “Love you P.R., keep your chin up!” The test pressings go on sale today at 12 p.m. Eastern; find them here.

“We recently repressed Rock and Roll Night Club and Pam Garavano-Coolbaugh, our Head Project Manager at Captured Tracks, asked what we should do with the tests,” Captured Track’s founder Mike Sniper said in a statement. “This conversation happened only a few days after Maria hit and it seemed like a no-brainer to help in any little way we could. Politics aside, these people need more help than they are currently getting.”

DeMarco joins the ranks of artists like Lin-Manuel Miranda and Beyoncé who have used their platforms to support Puerto Rico. Last week, Miranada released an all-star single called “Almost Like Praying” that raised funds for the Hispanic Federation UNIDOS Disaster Relief Fund. Beyoncé also released a track to benefit those affected by natural disasters—she remixed J Balvin and Willy Williams’ “Mi Gente,” donating the proceeds to aid victims across the Caribbean.
