I've been wondering about this as well. I too am a hermit, on the Eastside no less, so I don't exactly have my ear to the noise ground. However, there is the monthly Squall event at Kremwerk which last year had The Rita. There's one this weekend. I'm not sure if this is more noise or ambient or what but...

The only places I'm aware of that have noise shows is Kremwerk and Gallery 1412. I keep thinking there must be more but I just don't know of any. If anyone has any info, please let us know. Both Olympia and Portland have a fair amount of noise; I keep thinking Seattle does too but I can't always find it.
