Kudos to the Hamamatsu International Piano Competition! They've done a great job of providing streaming video, including archived video from completed performances, to piano lovers everywhere. You'll find the video here.
And, as if that weren't grand enough, the competition has it's own message board/forum for fans to discuss the HIPC. It's found here. The competition also has an interesting "news" site with running commentary on the performances and some "backstage" conversations with the pianists.
A pretty impressive jury will have their work cut-out for them with a full roster 94 pianists.
Best of luck to all!
