Expertly archived compilation (assembled by LA's Permanent Records along with Riding Easy) explores the wealth of proto-metal, pre-stoner lost rock tracks from the past 30 years. Brown Acid: The First Trip opens with the slithering buzzsaw guitars and hard-rock howl of Zeke's' "Box", a monster that gives Blue Cheer a run for their leaden blues. Snow sways into "Sunflower" with a touch of Steppenwolf's swagger and wind-in-their-hair wildness. Elsewhere, Zebra proves they were "Wasted" with a soul-inflected groove, while Bob Goodsite leans in on his wah-wah and phaser pedals, determined to out-Hendrix Jimi himself on "Faze." Raw Meat's "Stand By Girl" serves up a fierce, stomping riff intercut with Iron Butterfly style operatics. Bacchus kicks out a hostile sounding boogie, demanding to "Carry My Load." Josefus caps it all off nicely with a hooky power-pop meets Bob Seger System meets Lollipop Shoppe anthem with the undeniably catchy chorus, "hard luck - keep truckin'!"
