While the band has changed significantly since their debut, The Muffs' second album, Blonder and Blonder, sounds nearly identical to their first. It's all a brightly colored collection of fuzzed-out guitars,Kim Shattuck's screaming pop melodies and punk rhythms, delivered with just the right touch of abandon and just the right amount of polish. Even though the band is long-time friends withGreen Day, the repetition of the formula hits a little too close for comfort.Shattuck's songs aren't quite as strong asBillie Joe's, yet her hooks catch hold often enough to make Blonder and Blonder enjoyable for most fans of punk-pop.
