Sorry for the late notice, but just found this myself: tonight 6-8 pm Eastern USA time, you can jam along with other online musicians via the Web-based instrument PitchWeb. Let us know if you try it, because up until moments ago I knew nothing about this. This doubles as a virtual book launch party, to boot. The creators say, “Sit in from home at our book release party for Virtual Music: How the Web Got Wired for Sound (Routledge 2005). Make some virtual music of your own by joining us on Day One of Cathedral’s Deep Time, a year-long piece for servers.)
The book sounds on the bleeding edge to me — more like how the Web will get wired for sound, future tense, from where I sit. But you can jam on the bleeding edge with them. Report back if you do! (Via networked performance)
