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 decade, 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 of Brown Acid: The First Trip. Lance Barresi, co-owner of L.A.-cum-Chicago shop Permanent Records has shown incredible persistence in tracking down a stellar collection of rare singles from the 60s and 70s for the 11-track compilation. 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.
