With their girly background harmonies and Jilted John-like lead vocals, UK band Los Campesinos is what indie pop should be: Awkwardly cute. Forming in 2006, their use of violin, melody horn, and a glockenspiel allowed them to outshine the rest of the greasy indie pop bands with their unique dancey melodies. They’ve been on tour promoting their newest album, Romance Is Boring. They play Maxwell’s on April 17. $20. All ages. loscampesinos.com.
