Attention Prog fans– the music of Liars may take some getting used to, just because they don’t rely on any synths that whisk you away a la Yes or Rush (nothing wrong with that–after all they were the purveyors of the genre). But Liars seem a little angrier, not so much the class clown as the class troublemaker– yet possibly the ones more likely to cause a much-needed commercial music disturbance and break up all this indomitable emo once and for all. They alternate between the technical and anarchic, but aren’t above the subtle and sonorous. You might be able to determine whose mood dominates just by looking at the picture. Their upcoming and fifth album, Sisterworld, is due out on Mute Records in 2010. Indulge in their sprawling sonic canvas now on Red Bull Music Academy Radio.
