Fredric Jameson, a major figure in the thinking on postmodernism and culture, calls postmodernism "the cultural dominant of the logic of late capitalism", meaning that, through globalization, postmodern culture is tied inextricably with capitalism (Mark Fisher, writing 20 years later, goes further, essentially calling it the sole cultural possibility). Drawing from Jameson and other theorists, David Beard and Kenneth Gloag argue that, in music, postmodernism is not just an attitude but also an inevitability in the current cultural climate of fragmentation. As early as 1938, Theodor Adorno had already identified a trend toward the dissolution of "a culturally dominant set of values", citing the commodification of all genres as beginning of the end of genre or value distinctions in music.
