Some of the best thrills of the Internet music revolution is the ability to find extremely rare music with great ease. But even with such vast archives to draw from, quite a lot of great songs have gone undiscovered for nearly half a century — particularly in genres that lacked hifalutin arty pretense. Previously, only the most extremely dedicated and passionate record collectors had the stamina and prowess to hunt down long forgotten wonders in dusty record bins — often hoarding them in private collections, or selling at ridiculous collector’s prices. Legendary compilations like Nuggets, Pebbles, ad nauseum, have exhausted the mines of early garage rock and proto-punk, keeping alive a large cross-section of underground ephemera. However, few have delved into and expertly archived the wealth of proto-metal, pre-stoner rock tracks collected on Brown Acid.

Lance Barresi, owner of L.A.-based Permanent Records and the Permanent Records Roadhouse has shown incredible persistence in tracking down a stellar collection of rare singles from the 60s and 70s for the growing compilation series. Partnered with Daniel Hall of RidingEasy Records, the two have assembled a selection of songs that’s hard to believe have remained unheard for so long.

“I essentially go through hell and high water just to find these records,” Barresi says. “Once I find a record worthy of tracking, I begin the (sometimes) extremely arduous process of contacting the band members and encouraging them to take part. Daniel and I agree that licensing all the tracks we’re using for Brown Acid is best for everyone involved,” rather than simply bootlegging the tracks. When all of the bands and labels haven’t existed for 30-40 years or more, tracking down the creators gives all of these tunes a real second chance at success.

“There’s a long list of songs that we’d love to include,” Barresi says. “But we just can’t track the bands down. I like the idea that Brown Acid is getting so much attention, so people might reach out to us.”
