Actually, early in the thread, you folks were discussing making and distributing CD's with samples of songs. It's a terrific idea, and it's been done before, too!
Check out this Operation Disque Drop:

I think he said he was a member of AAm-- anybody know?
Anyway, burning "mystery disks" that have some song samples and something like "Tangy Pop -Alizee" scrawled on 'em, maybe a hint to go to youtube, disquedrop, or here. That'll get some converts. One at a time, but hey...
The poster idea is cool too: what if we had a .pdf or two of posters or stencils here to download and start plastering/painting our towns with? Hint, black and white is better for cheap, mass copying, but heck.
