Kurt Andersen talks to author Daniel Torday about his new book, “Boomer1,” a dark satire about the tension between millennials and baby boomers coming to a head. Then a segment about something boomers couldn’t stand about the generation that preceded them: its love for Lawrence Welk’s unapologetically wholesome variety show. For our Guilty Pleasures feature, listener Paul Fotsch explains how he couldn’t stand Lawrence Welk as a kid but grew to love the show. And finally, Argentine experimental musician Juana Molina performs songs from her album, “Halo.”
