Justin Davidson comes away from ArtsJournal’s online conversation between music critics on ideas and music impressed with the diversity of the landscape. “Over a discussion that meandered through Brahms and Wagner, early medieval polyphony, Sonic Youth, Bjork, Mozart and the evils of 12-tone Modernism, a picture has emerged of a musical world in which each composer – each piece, even – must create its own context from scratch. There are no rules, no lingua franca, no constraints within which an artist might find freedom. The scaffolding of prevailing ideas has fallen away.”
