You know how sometimes, when you eat a piece of cake, the frosting is really, really delicious, but the cake itself is kind of average or dry? That’s how I felt about the Yeah Yeah Yeah’s newest album, “Mosquito.” After waiting over a month and four years, playing their three previous studio albums and numerous EPs over and over again, I couldn’t wait to get my hands on some new YYY songs. They released their first single off the album, “Sacrilege,” about a month and a half ago, a fantastic song true to their rebel-rock sound that showed promise of a great new album. I couldn’t stop playing that song — or rather, blasting it in my room — and I’m sure the girls who live in my hallway can attest to that.
