Nothing succeeds like excess in of Montrealâs hyperkinetic sonic world. Wielding a vast, polysyllabic vocabulary (e.g., âYou fetishize the archetypeâ) and flexing vocal acrobatics that extrapolate on Prince, Todd Rundgren, and Russell Maelâs mannerisms, mastermind Kevin Barnes leads his Athens, Georgia, bandmates through maximalist art-pop and blown-out R&B productions thatâll douse your highbrow with sweat. The new Paralytic Stalks is a disorienting blast of prog-rock extravagance that sounds like $1 million in loose change.
