One other note on the Revueltas' '8 x radio' video: at 4:30 you notice the musicians (especially the cellist) smiling. This is really one of the few classical music pieces that I know of that make both musicians and the audience smile, for different reasons. I can talk about the composition, its notation, the history of the composition, Revueltas' tongue-in cheek comments on the composition, and what not. It doesn't matter really, because the effect of this piece is the same. Silvestre Revueltas 8 x Radio
