Lo and behold, Brown Acid – The Fifteenth Trip is here, and it’s another mind-melting dose of brilliant long-lost, rare, and unreleased hard rock, heavy psych, and proto-metal tracks from the ’60s -’70s. Riding Easy’s crate-digging mining expeditions, and growing network of the original artists keeps on giving with more and more incredible discoveries every time they go back for more. Like they’ve done throughout this series, all of these tracks were painstakingly licensed legitimately and the artists were paid. Make oneself comfortable and prepare for yet another deep, deep dive into the treasure trove of dank, subterranean, wild-eyed and hairy rock ’n’ roll of yesteryear. Some key examples include: As usual, this Trip opens strong, as “Take The Time” swaggers along with switchblade stabs of guitar twang and frantic drumming that sounds like Nick Cave’s ’80s post-punk barbarians The Birthday Party on this 1969 single from the mysterious Boston area band The Looking Glass. Negative Space toil in the dark web of The Seeds, and dwell in the mystic haze of working class suburbs in Camden, NJ circa 1970. Their angry, nasty guitar sounds and frustration-bogged frontman Rob Russen ensure that the aggro fueled “Forbidden Fruit”—in which he confesses his love for his sister-in-law—will hit one right in the face. Truth & Janey might be familiar from their 45-only “Midnight Horseman” single heard way back on the Sixth Trip, and / or their incredible 1976 album No Rest For The Wicked. Their super-driven soul leaning cover of “Under My Thumb” is almost like The Who had penned the track, with relentless drums, jackhammer rhythm guitar and near-falsetto vocals.
