The Besnard Lakes are experimenters, explorers of sonic textures and the fearful symmetries of pop. What they are more specifically is hard to describe. They’re noise rock that doesn’t alienate so much as woo, or psych rock that makes things look clearer rather than distorted. They’re the musical summit of the Velvet Underground’s woozy pallor and the Beach Boys cartoon harmonic brilliance. They’re all of these things and none them. Sometimes they manifest as a neat rock fourtet, at other times their composition is a sprawling ensemble of horns, keyboards, guitars, strings and women’s choir. The only imponderable is how stunning the performance will be.
