The Wombats’ gift of making indie pop sound fresh and effortless continues unabated on its fourth album. Guitars shine like mirror balls, rhythms invite fresh dance-floor poses, and sky-high vocal melodies inspire the kind of sing-alongs that ensure you extra space on the bus. Their penchant for clever wordplay might cause head scratches—cue “Lemon to a Knife Fight” and “Out of My Head” for prime examples—but make perfect sense in The Wombats’ world.
