35 years ago, composer Philip Glass unleased an opera on the music world that was completely unlike anything that had come before. It's a safe bet that Puccini or Rameau would have been completely bewildered by a plotless work with no breaks, and text consisting mostly of solfège text and numbers. Heck, we're pretty sure audiences 35 years ago were bewildered, too, even by 1970s standards.
Glass went on to write a string of theater works that all bear his distinctive musical stamp, even as their plots grew more mainstream.
