The eighth album from Pennsylvania’s Dr. Dog plays like a corroded artifact from the ‘60s—a sublime, harmony-filled rock record that’s turned toxic and warped with age, dredged up from some muddy, forgotten river bank. The truth is that this trippy, sprawling saga was released in 2008, as a reshuffled version of the band’s unreleased 2001 debut. It’s a lo-fi treasure of rusted outsider rock, spangled with glittering, off-kilter synths (“Bring My Baby Back”), wonky, water-logged pianos (“Fire on My Back) and eerily romantic bayou doo-wop (“Swamp Descent”) — in other words, a record to relish.
