Hailing from Philadelphia, Hop Along features the slightly unhinged voice and guitar work of Frances Quinlan. The trio’s prickly, volatile songs give its debut, Get Disowned, the feel of a group therapy session fused with a coffeehouse jam. Quinlan’s blend of abrasiveness and vulnerability brings such quirky artists as Kristin Hersh and Joanna Newsom to mind; her band’s loosely strung arrangements suggest everyone from Danielson Famile to The Shaggs. The gnarly sounds coursing through “Tibetan Pop Stars,” “No Good Al Joad,” “Young and Happy!,” and similar tunes reinforce the album’s emotionally conflicted lyrics. Quinlan murmurs, bellows, and plays fast and loose with pitch as she recounts unsettling childhood memories (“Trouble Found Me”), considers elusive love (“Kids on the Boardwalk”), and eulogizes a lost soul’s death (“Sally II”). Out of the prevailing sonic tumult emerge unexpected hooks and rhythms, like the slippery R&B groove beneath “Laments.” Ultimately, Quinlan and her cohorts infuse Get Disowned with an irrepressible joy that makes its most cacophonous moments go down easily.
