In 2016, Taylor Mac performed a one-time-only, 24-hour immersive theatrical experience in front of a live audience at St. Ann’s Warehouse in Brooklyn. The concert offered an alternative take on U.S. history, narrated through music that was popular from the nation’s founding to the present, with Mac transforming hourly by changing into elaborate, decade-specific costumes by Mac’s longtime collaborator Machine Dazzle. The documentary, TAYLOR MAC’S 24-DECADE HISTORY OF POPULAR MUSIC, captures Mac’s marathon performance in New York, alongside footage from other shows on the tour, which played throughout the world. In the show, Mac and 24 musicians interpret 24 songs, from “Yankee Doodle” to “Gimme Shelter,” “Born to Run,” and “Gloria,” with one performer leaving the stage each hour, until Mac is on stage alone in the final 24th hour.
