As a follow-up to their similarly fluffy ’99 debut, Pink Hearts Yellow Moons, and 2000’s The California EP, Sound Go Round isn’t a big departure for this bubblegummy, pop-loving Denver quartet. But, hey, you don’t mess with the cotton-candy machine when it’s working. Especially not when it’s landed you a few choice cuts on the Power Puff Girls soundtrack.

That’s not to say there aren’t a few surprises here. An ’80s prom-night disco-ball synth breakdown pops up on "All the Colors." And Rob Greene’s fuzzed-out bass bottom keeps everything from getting too cuddly. But mostly, Sound Go Round is singer/guitarist Tammy Ealom’s chewy girl-group melodies wrapped in just the right amount of jangle and bounce. And Ealom has an ear for hooks, whether Dressy Bessy are rocking out on "Carry On" or playing it cool, as on "I Saw Cinnamon."
