As with most thing literary, musical, or artistic, once you get into the 1970s I am out of my element. My wheelhouse is Arthur Marwick's long decade of 1958 to 1974. Check out Marwick's book on The Sixties. Well, I am hearing good things about Bruce Conner and the 1970s. Apparently he was on the top of his game throughout the decade. Warhol, Burroughs and the Rolling Stones were crap after 1974 if not before. As were Hunter S. Thompson, the Who, John Ashbery, and Black Sabbath. Based on the intel I am getting from solid sources, I'll give Conner the benefit of the doubt.
