“The Big Broadcast!,” an annual variety show based on commercials, radio stories and music from the 1940s, has been bringing Mount Holyoke back to the age of swing for over a decade. Mark Gionfriddo, director and founder of the Mount Holyoke Jazz Ensemble and creator of “The Big Broadcast!,” worked with his student production team (Chris Cassidy ’20, Megan Ferrara ’20, Mara Kleinberg ’22, Anna Morris ’20 and Julia Sienkiewicz ’20) to bring this year’s show to life.
