who were the most important artists of the 20th century, and what were the most important art forms? oh you can advocate for, maybe, james joyce, or picasso, or pollock, or henry moore, or mies van der rohe, or something. here are my candidates: louis armstrong, muddy waters, hank williams, grandmaster flash, bill monroe, bob marley, fela kuti, thomas dorsey, eminem, aretha. popular music was the dominant art form of the century: the one with the biggest audiences and the actual effects. also, it was the source of century's greatest beauties and most pointed challenges to various conceptions of beauty. you can pretend that novels re-articulate lives, but i bet you and your friends could almost tell the story of your lives in songs. maybe it's hard to compare hank williams to schoenberg, much less picasso, but hank's music was so very much better, so very much more important to so many more people, so comparatively human, so democratic, so vastly more beautiful, moving, and challenging. so more true.
