Brown Acid - "The Seventeenth Trip" LP

Kicking off this trip, Grapple’s “Ethereal Genesis” is a heavy psych gem from 1969 written by J. Bruce Svoboda, a.k.a. Jay Bruce, formerly of The Hangmen and The Five Canadians (who were actually the same San Antonio band). The latter’s 1966 garage favorite “Writing on the Wall” has been endlessly covered, but Grapple were never heard from again.

With a guitar riff that blatantly rips off Sabbath’s “Black Sabbath,” Image’s mostly instrumental lysergic obscurity “Witchcraft ’71” (originally unveiled that very year) also boasts a horror-movie organ intro, a voodoo drum break and some championship chanting. Private press heads might recall late Image drummer John Beke from his ’80s reemergence with country rockers Crossfyre.

Stone Hedge were a seven-piece rock band out of Michigan with a penchant for Creedence and anthropomorphism. “Smokey Bear” is their 1972 tribute to the official mascot of the U.S. Forest Services—not to mention the A side of their sole single—and it recalls the kind of organ-drenched swamp jam that soundtracked many a Burt Reynolds flick back in the day.

If you think being a Southern rock band from Milwaukee doesn’t make much sense, that’s probably why Crossfire changed their sound along with their name—to Bad Boy—after signing with United Artists. Bad Boy’s severely underappreciated second album, Back To Back, is a 1978 hard rock jewel, but you can hear their boogie-woogie roots on this rare 1975 single.
