Jimmy McDonough: Jimmy McDonough is a biographer and journalist.  He is perhaps best known for his biographies of Russ Meyer, Andy Milligan and Neil Young.  He is noted by critics for his remarkably exhaustive accounts and for his tendency to avoid romanticizing his subjects' lives.  For this reason, he was described by "The Times" as "a literary Terminator". " Time"' s Richard Corliss declared his first published work "The Ghastly One" "a masterpiece" and John Waters has repeatedly named it one of his favorite books(this was actually McDonough's second effort; the first, "Shakey: The Biography of Neil Young," had been held up by a lawsuit over the claim that Young had tried to prevent publication).  Other reviewers decry the inclusion of his personal experience/reactions often found in his books as a sort of biographical treason.  In addition to the aforementioned biographies, McDonough has authored profiles on Jimmy Scott, Gary Stewart, Hubert Selby, Jr., the Ormond family and Link Wray, and over the span of his career he has written for a number of publications including: "The Village Voice", "Film Comment", and "Variety".
