Gene Simmons says the rock business is dead

I think Bowie was the first with the big stage show, although
there might be some overlap. Before that, major artists would
just come out on the Filmore East stage in T-shirts and play the
most incredible (rock) music the world has ever heard. Funny -
Hendrix, Sly, Joplin, Cream, Tull, Creedence didn't seem to need
fireworks, guys running around in gorilla suits, makeup or
explosions to hold an audience's attention. I wonder why. Well,
Joplin and Hendrix didn't wear T-shirts, but the point is the
same. In fact, they dressed rather alike, now that I think of
it. The San Francisco thing, I think.
