The creative act is not performed by the artist alone; the spectator brings the work in contact with the external world by deciphering and interpreting its inner qualifications and thus adds his contribution to the creative act. - Marcel Duchamp
Pietro Psaier did well for an artist, selling over 5,000 paintings in the last 10 years and grossing well over a million pounds from auctions. He traveled the world and regularly hung out with famous artists like Andy Warhol and John Lennon.
However, Pietro Psaier probably never existed and attempts to verify his identity have been fruitless.
Does it even matter if he was real or not?
We buy emotion, not product details.
We care about Evel Knievel not because he jumped X number of feet, we care about him because he jumped over 19 cars. Same distance, but using something we could easiliy visualize (the cars) instead of hard details (distance), he was able to capture our imagination by triggering an emotinal response.
The better you craft the emotional context that people experience your music through, the better people will pecieve your music.
So go ahead, crate fake persona or start a beef with another band.
Be an entertainer.
