The problem with most music today is that it just isn’t psychedelic enough. Of course, grim times call for politically engaged art, but just as crucial to societal well-being is escapist, mind-altering music. That’s where Residual Echoes come in, resurrecting the sounds ricocheting through the Fillmore of your wildest daydreams. The thirteen-minute “Slant” starts the disc with tension-building bass pulsations, spacey reverb, rumbling drums, phlegmy Lemmy growls, revving guitars à la Hawkwind or the MC5 — all failsafe psych-rock tropes that always inspire head-waving and lighter-banging. The track finally evolves into a skronking, lung-bursting freakout, and you may think Residual Echoes’ wad has been shot. Uh-uh. The similarly epic “Diamond Drops” builds rippled metallic hurricane winds recalling J. Mascis’ caustic fretwork, while elsewhere, touchstones like The Velvet Underground & Nico, Sonny Sharrock, Jimmy Page’s acoustic passages, and Spacemen 3’s Perfect Prescription parade through this blustery, bulbous attack like welcome old pals doling out microdots. High and mighty.
