Pop culture is full of fictional bands singing songs purpose-made to capture a moment, a sound. This music doesn\u2019t organically emerge from a scene or genre, hoping to find an audience. Instead it fulfills an assignment: it needs to be 1960s folk music, 1970s guitar rock, 80s hair metal, 90s gangsta rap, and on and on.\nIn this episode, we\u2019re going to use \u2018Stereophonic,\u2019 which just opened on Broadway, as a kind of case study in how to construct songs like this. The playwright David Adjmi and his collaborator, Will Butler formerly of the band Arcade Fire, will walk us through how they did it. How they made music that needs to capture the past, but wants to speak to the present; that has to work dramatically but hopes to stand on its own; that must be plausible, but aspires to be something even more.\xa0\nThe band in Stereophonic includes Sarah Pidgeon, Tom Pecinka, Juliana Canfield, Will Brill, and Chris Stack. Stereophonic is now playing on Broadway\u2014and the cast album will be out May 10.\nThank you to Daniel Aukin, Marie Bshara, and Blake Zidell and Nate Sloan.\xa0\nThis episode was produced by Max Freedman and edited by Evan Chung, who produce the show with Katie Shepherd.
