The first gallery here is from a duo recital by Martha Argerich and Nelson Freire, which I attended at the last minute, getting chorus seats (for $5).
  The 2nd one includes snapshots taken of curtain calls from a San Francisco Symphony, Davies Hall orchestra seat, after the Ravel on March 7, 2009 plus links to other records of the occasion.
  The third one is a series of screen captures from a Live streaming of a concert from Verbier, Switzerland July 22, 2008. Amazing technology. The sound was terrific. Maybe I'll have an audio segment from that later.
