Right now I’m listening to a live piano performance by Imogen Heap (she calls it “piano noodlings”) being broadcast over USTREAM, announced over Twitter a few minutes ago.

Several hundred other people are watching too, and it’s a new kind of musical experience thanks to the real-time Web. People have spoken of it before, and this is a fascinating aspect of it.

We can all sit down in front of the computer in our individual homes and listen to an Imogen Heap concert, live, together. It’s not quite the real thing, of course, but it’s different. Good different. It’s simple, spontaneous, and inclusive.

I can’t wait to see what other artists and other game-changers come up with in this next era of the Web.
