Here you go. I am long overdo to post something on YouTube with Measha Brueggergosman and what do I find? This performance of Measha singing "Aria" by John Cage while the orchestra plays something else entirely took place at Carnegie Hall on April 15, 2009. The guy talking is Michael Tilson Thomas.
This represents the intersection of a few different strains. Being something of a modernist at heart, I absolutely love this. Enjoy.
