But it wasn't always so. This music was once considered unmarketable, even dangerous. It was practiced in garages and back alleys as far from the mainstream as it's possible to get. Not unlike the early Internet, if you think about it. In both cases, something obviously happened between then and now.
Enthusiasm is irrepressible.
So is life. Left to themselves, both emerge unbidden from the materials at hand. We are living proof of the proposition. And perhaps more than any other form, ecstatic social music taps the fundamental human drive to celebrate the outrageous fact of our existence. The reason rock and roll will never die is that, when you get down to this level of things, nobody's taking any wooden nickels.
