I think there’s a lot of good music out there, but referring to true original artists, specially in rock, I don’t know.
Maybe the last band with their own style was Radiohead, Tv On The Radio is really interesting also, but are they original?
Was Kid A the first album of that kind? “Krautrock� scene existed since late 60’s and I guess Yorke and the rest listened a lot of that before making that album.
On of Tv On the Radio’s case, their work can sometimes be similar with some Zappa’s albums, one for example: Does Humor Belong to Music from 1984.
Other bands like The Strokes, The White Stripes, Interpol, The Mars Volta, The Darkness, Coldplay to name a few have clear influences from other bands, and in some cases the steal is obvious, in my opinion.
Are true original rock artists still out there?
Any point of view is valid.

at this point i don't think it's really possible for any rock band to gain a recognizable level of popularity by being truly original. even the examples you cite fail at being true originals. sure Kid A was a departure and distinguished radiohead as more than just another brit pop band but that was also their 4th major release and it's not like OK Computer didn't sell a copy or two.

you can still find remarkably fresh albums from 'rock' bands but as far as finding a truly original rock band, i'm not holding my breath. i think rock music is far too entrenched in the popular culture of the teenage generation to ever truly become original again regardless of what any press release tells you.

it seems to me that most rock bands or musicians calling themselves original or experimental are doing so based on the fact that their main influences aren't played on mtv and they're not expecting more people to recognize that. which begs the question, who are they trying to impress?

Well, that's pretty much the entire history of experimental/progressive rock, for the most part.

yeah but i was bitching about the myspace types who call themselves the same

and besides why does prog or experimental have to root itself in rock?

its all been done before, just pick the version you like the most

Yeah and I´m not talking only about mainstream bands, but also those called "indie" bands as well.
Fair enough, there's nothing new now, but have we crossed the line where there is nothing new to tell or invent?
What will happen then, to copycat ourselves from here to eternity?
That's very discouraging.

The point of originality is that you're doing something no one's thought of before. So of course we can't predict where rock is going to go next, if we could, we'd be doing it ourselves, and we'd be the original ones. I think I'll go with the statement that it's always possible to be original. I don't think a form of music as broad as "rock" can be milked dry.

It depends on how specific you want to get. For instance, if your looking for just combinations of notes, wasn't there a composer who did all of them hundreds of years ago?

I think we have been copycatting ourselves for a long time and this can only continue. With every artist you can trace their sound back to an influence and that influence to another influence. Where does it end? I guess you can say the Blues and Jazz for modern music.

But this all depends on your definition of originality. If it doesn't need to be a very strict definition then yes, things will continue to keep twisting into new territory.

Plus who knows what is possible in the future, electricity is a fairly new invention in the grand scheme of things and just look what that did for music.

You can be influenced by others and still produce original, unique sounding music. Just about everyone, if not everyone, has taken some influence from others even the most original of musicians.

I think there is quite a few bands out there (mainstream even) that I would say have sound that is their own and thus play original sounding music.

Obviously, all of the available guitar riffs had been used up by 1981. Everything that could possibly be invented to improve our collective lives had already been invented by 1993.
