San Francisco (by way of San Rafael) proto-metal band Orchid has flawlessly tapped into the early-'70s vein of doomy occult rock akin to Pentagram and Black Sabbath, with nary a modern-day anachronism. From the vintage guitar tones to lead singer Theo Mindell’s high-wailing vocal register and a hard-driving rhythm section, it’s hard to believe that Orchid didn’t hatch its debut 2009 EP, Through the Devil’s Doorway, back in 1971. “Into the Sun” opens with what could only be a vintage Gibson guitar blasting through either a vintage Marshall Plexi or a similarly hulking Orange amplifier, as Mindell croons with wicked inflections recalling a young Bobby Liebling. “Eastern Woman” opens with droney, Eastern-influenced tones before Mark Thomas Baker hammers out some chugging Sabbath-esque riffs. “Son of Misery” follows, with more doomy dirge tones rumbling from bass player Keith Nickel while Mindell sings through murky “Planet Caravan” effects to make for a song that sounds like an appreciative nod to bygone Australian hard rockers Buffalo.
