there is a soundproof performance hall inside of the seattle library. no one was performing when we were there, so the soundproof ceiling was not needed. this shot is taken by my brother from the regular 3rd floor of the library. i had to jump over a little divider to get into the stadium seating of the performance hall, but the library employees didn't have a reaction more severe than annoyance. unfortunately there was not enough light to get any usable shutter speeds.
