In his first full-length play since last year’s five-hour epic, The Lily’s Revenge, downtown activist-playwright Taylor Mac is back with another tome melding politics and glitter: The Walk Across America for Mother Earth. The show, with music by Ellen Maddow of the Talking Band, is inspired by Mac’s participation in a trek from New York to the spot, 65 miles northwest of Las Vegas, where the government had been testing nukes since 1951. The program finally halted in 1992, the year of the nine-month protest walk, on which Mac met the hippies, anarchists, and radical faeries that became this play’s main characters. The Talking Band’s Paul Zimet directs.
