Rick and catspaw, Y'know it sorta hits me as visual "Muzak". We all know that the music in Muzak is technically excellent -- but so damn homogenized it lacks any feel.
When we're at a contra dance, or bluegrass concert we really want the visuals that make the experience complete. I mean, man, if we wanted JUST the music of the experience we'd stay home and spin CDs. We want to be reminded of our humanity and, god forbid, want to have some romantic notions that technology (including "improved" violins) aren't going to homogenize the whole damn world.
