“One thing that’s for sure / Though we never found a cure / We can ride out heartbreak like the weather,” sings Sam Misner, one half of the unclassifiable Northern California duo Misner & Smith, on the group’s new single, “Anthem.” Along with his longtime musical partner Megan Smith, Misner set about writing the tune that would eventually become the first single from Misner & Smith’s upcoming LP All is Song by dissecting the idea of anthemic music itself.
