Mac DeMarco has put four test pressings of his 2012 album Rock and Roll Night Club up for sale in a bid to raise money for the people of Puerto Rico who are reeling from the devastation caused by Hurricane Maria.

The rare records are available on Discogs and DeMarco’s record label Captured Tracks have kindly agreed to match the Discogs donation with $250 per record. The money raised will be sent to the Caribbean hurricane relief initiative Waves for Water.

Each message on the four rare records will have a different and unique message, “love you P.R., keep your chin up!” he added.

“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.”
