Lets pretend all your performance anxiety and lack of musical talent just withers away. You now have the ability to perform one song (and play any instrument for that song) flawlessly. There is an audience of 100,000+ people waiting for you who are all die hard fans of whatever song you happen to chose. What song would you pick?
My choice would be Born to Run. If god wrote a rock song meant for the stage it would sound exactly like that.
A hundred thousand people who are keyed up to tune into the music that stems from an absence of instruments. Not the incidental pauses between pieces but focused silence and attention to sound that inescapably escapes into the room. Not a smattering of folks who read the wiki article and have to put up with otherwise bored folks making noise or conversing nonetheless, but a hundred thousand folks who are die hard fans of the concept. A hundred thousand participants. Being at the epicenter of that would be mind-blowing.
