The so-called Chicago Audio Fest mentioned on AA is a show someone else is trying to organize.

And I imagine something on a grander scale could work, too.

Steve, I don't need no neon runnin' lights on my speakers, they be big enough to attract the ladies on their own, fo' shizzle!
I agree about Simon Yorke and would add a few others such as Kuzma Stabi XL, La Platine Verdier, and SPJ La Luce to the list.
