The artist is, by himself, the biggest and most important instrument to his own work. He's the designated spokesman of what his music is telling us.
The instrument ends where the artist does. He does his job on this planet, leaves his mark and rests in peace.
It's not about the musical instrument; one can be a very skilled guitar player and play the most complex theoretical-mathematical-orchestral-classical songs, but if he has nothing in mind, no vision of his own, then he has nothing to tell to the rest of the world and therefore he cannot create (art).
There's no artist where there's no originality. Each story has a unique symphony and rhythm : if you can give it a unique form, make it shine up and down and bring us through its radiance, then you've made a true work of art. Only an artist can be such an instrument for such creative work.
If one cannot guide the rest of the world with his music, then he's the instrument for nothing. It's just a playful thought, a hobby and not a life purpose.
I have total respect for someone who admits that than someone who pretends to be an artist, sell his trivial crap on bandcamp and promotes it all over the place like 95% of the people I see on the Internet.
p.s. I don't give a flying fuck about your opinion. Take it or leave it, you bunch of robotic pseudo-intellectual self-feeding marketing business-interested freaks !
