Nate Ruess' songs imply that he's been dumped a zillion times. The articulate lead singer/songwriter of Fun. — a trio also featuring Andrew Dost of Anathallo and Jack Antonoff of Steel Train, the opening act — details the minutiae of crushes, heartache, and self-doubt in theatrical streams of consciousness. The band's 2009 debut, Aim and Ignite, is full of songs such as "At Least I'm Not as Sad (As I Used to Be)," which pairs neurotic, self-deprecating lyrics with twinkly, carnivalesque pop elements. A digital edition of the album includes the music video for bouncy single "Walking the Dog," which features Ruess' cartoonish good looks and elastic voice at their emo-in-Technicolor best.
