It's coming, and WXYC will not be participating.
Some guy from England named Bill Drummond has decided November 21st should be No Music Day. He cites stagnation in musical creativity as one of his primary reasons and hopes that a day of silence will kick-start something really new. I think he's not listening to the right stuff (does he have the Gordon Monahan and Tim Hecker releases that graced WXYC's rotation this year?), or maybe he's forgotten how to listen.
He has a point that there's a lot of musical fodder out there, but after reading his rant I personally think his idea is silly and contrived. So, despite the fact that London's excellent Resonance FM is participating, I'm glad that we are not.
I believe you can make a much more meaningful (if still futile) statement by participating in Buy Nothing Day this Friday.
