Afterparties - repost

I wonder what an after party for an orchestra after-party would be like. Pretty boring stuff probably. I wonder what would happen if people got mixed up and instead of going to the after-party for the orchestra, they went to the after-party for Nine Inch Nails or Marilyn Manson. Now that would be amusing. I'd be like mixing Handel's Messiah and Anti-Christ Superstar.
