“Asking me if I’m homosexual is like asking James Brown if he’s black.” So crowed the American glam-rocker Jobriath as he commenced his career in the early 1970s. Backing up the faggy hubris was Jobriath’s musical talent (he was a classical piano prodigy) and his shameless manager, who unleashed an avalanche of hype—from Times Square billboards to full-page ads in Rolling Stone and Vogue, all before one note of music had been released—that would ultimately prove ruinous. In Jobriath A.D., documentarian Kieran Turner tracks this incredible tale through archival and contemporary interviews, gracefully plot-forwarding animation, and dazzling performance footage.
