John Cameron Mitchell and Glenn Close are co-hosting an eight-hour listening marathon of their wild podcast musical, “Anthem: Homunculus” on Nov. 24 at the IFC Center.

The event will feature guest appearances, live musical performances, food and cocktails.

The podcast includes 31 original songs, 30 musicians and 40 actors, including Close crooning a tune while nailed to a cross, Patti LuPone as a “junkie nun” and Cynthia Erivo as “Joan the Baptist.”

Admission is free with limited tickets available via TodayTix — and fans can listen via the Luminary app.
