“Battlesong of Boudica,” an epic revenge tragedy starring award-winning fight choreographer Jen Albert, runs from Sunday, April 9, through Sunday, April 30 at the Hudson Backstage. Taken from the history and legend of the Iceni warrior queen Boudica, famous for her uprising against invading Romans in 61 A.D., the production is an ancient saga of the iron age, a primal spectacle of power and revenge told in song, spoken verse, dance and theater. Showtimes on April 9 is 7 p.m. and a pay-what-you-can performance will be held on April 10 at 8 p.m. Regular showtimes are 8 p.
