There's that music that teenage girls love. It has a pleading voice and earnest lyrics. It's catchy, and its platitudes stick in naïve minds like Hubba Bubba in braces. The piano-heavy pop on Pardon the Invasion by local four-piece Sometimes Three sounds more like coming-of-age music than slick, super-produced power ballads. On "Fade," lead singer Chris Accardo's urgent, heartfelt lyrics (The edge is near and your curtain falls away/The edge is near and your star begins to fade) and imploring piano chords, ripped almost straight out of Coldplay's "Clocks," combine to make a public-service announcement aimed at the pubescent set. That announcement: Everything is going to be OK. Invasion is clean, light, familiar — the kinds of songs fit to provide the soundtrack for vernal make-out sessions or for moments when really big shit happens — like crashing Mom's minivan into the garage door.
