Let's get the labels out of the way. Tegan and Sara are 24-year-old lesbian twin sisters from Canada who have been making music for almost a decade. None of which says anything about their music, a kind of acoustic indie-pop icing delectable enough to make sweet the seething mass of insecurities and obsessions that lie beneath.
You Wouldn't Like Me and So Jealous are just two of the self-loathing tracks, Speak Slow has a new-wave, Elvis Costello bite to it. Tegan and Sara's voices are equally cutesy but while one is cosy and hopeful, the other is only a kitten-heeled step away from a bolshy banshee.
Vocally weaving and ducking, they drag up memories of Voice of the Beehive, or a Siamese version of Susannah Hoffs from the Bangles. What stops them becoming an annoying pop hydra is their unadorned directness and sharp pop hooks. "The same as I love you/ You'll always love me too/ This love isn't good unless it's me and you," they sing in I Know I Know I Know, eternal Shirley Temples forever forcing affection.
