Originality existed at some point, as evidenced by Beefheart, Sun City Girls, Thinking Fellers, Xenakis, Throbbing Gristle (who I'm not even really a fan of!), Caroliner, The Residents, Harry Partch, Glenn Branca, and a few others. Sure, those artists weren't "original" 100% of the time, but they did reinvent music in some way.
In the world we live in in 2009, with the INFINITE disposal to us of instruments, effects, recording programs, VST plugins... there's really no reason any two bands should sound much alike at all. And I do see and hear somewhat original bands every now and then but none strike me as much as some of the artists I listed above.. and those are the artists that will stand the test of time, even if no one gives a fuck about them right now.
