In case you wanted to get some clarity around what a Mexican "ranchera" is. Here's one example from Lila Downs. Of course, it's got some hip hop inflections in the middle of it. But hey. We live in a pomo culture.
The purpose of this essay is to examine the aesthetic behind Cage's "silent" composition, 4'33", to trace its history, and to show that it marked a significant change in John Cage's musical thought -- specifically how it forms a point-of-no-return from the conventional communicative, self-expressive and intentional purpose of music to a radical new aesthetic that informs the field of unintentional sound, interpenetration, chance, and indeterminacy. The compositional process is described, both the writing of 4'33" and its evolution from past thought. Implications for performance are examined.
