A “side pony,” the hairstyle that Lake Street Dive’s Nonesuch debut is named after, is the kind of one-sided Cubism-worthy ’do that requires unwavering self-confidence to pull off. The foursome is not referring to the demure, swept-to-the-side fashion Taylor Swift occasionally sports, but more the outré look of, say, Napoleon Dynamite’s friend Deb. However, a side pony, for them, is really a metaphor for their philosophy and personality as a band, one that seamlessly incorporates R&B, pop, ’60s-era rock, and soul into a unique, dance-party-ready mix. As bassist Bridget Kearney puts it, “When we were settling on the album title, that one just stuck out to us as embodying the band’s spirit. We’ve always been this somewhat uncategorizable, weird, outlying genre-less band. That’s the statement we wanted to make with this record: be yourself.”
