THEATER/MUSIC/MULTIMEDIA: Backed by the indie rock band Gloria Deluxe and plenty of ingenious stagecraft, the otherworldly singing of Cynthia Hopkins is at the center of this swirling tapestry of music, theater, video and dance. Blurring lines between confession and performance, concert and play, the Alpert Award winner intertwines two narrative threads: the final show of a fictional ’70s-era cult-pop singer before her mysterious disappearance, and her daughter’s making of a documentary film, many years later, about the mother she never knew.
