Sirens Sister is a band that succeeds in surpassing one's initial expectations. Despite having a certain air of mystical, Earth Mother uncoolness, the band's songs are wiry, nervy trains of crazed headlong rock momentum. They strike an easy balance of quite radio-friendly modern rock and a respect for dark '80s pop figures like Echo and the Bunnymen and the Cure. The lead vocals are convincingly histrionic, evoking a number of singers known for projecting to the back of the room, notably Jeff Buckley. It's the kind of music that either doesn't translate to a live representation, or, more likely, thrives on the energy an audience supplies. Regardless, Sirens Sister goes for broke, and their in-store at Rocket Records should be a sight to see.
