Cults has always been a band to look to both past and present. When the young duo arrived on the New York scene in 2010 with the perfectly formed debut single “Go Outside,” it was described as Phil Spector with hip-hop sensibilities, glee soaked in reverb. Sometimes, when Madeline’s friends heard the song, they asked her how they got little boys to sing on it. “That’s just me!” she told them. In fact, if you ask Brian to name his favorite album, he’ll name Home Schooled: The ABCs of Kid Soul, a compilation by the Numero Group, a collection of lost, old R&B recorded by children.
