The goth rocker – who is showcasing his watercolours in Vienna, Austria alongside short films by U.S. film director David Lynch – admitted he was apprehensive about seeing his work displayed for people to criticise.

Speaking at a preview of the ‘Genealogies Of Pain’ show at Vienna’s Kunsthalle, he said: “I feel very comfortable when I’m on stage in front of thousands of people. However, it’s quite frightening to come into a room that is full of my pictures and people looking at them.

“Art gives me the freedom I don’t have when I make music. In music you feel a connection to the voice and think about the person behind it. In art that’s secondary.”

The ‘Disposable Teens’ hitmaker – who is engaged to actress Evan Rachel Wood – admitted he is so protective of his art, he won’t show anyone his work until he is completely satisfied with it.

He added to Austria’s Kurier newspaper: “When I finish a picture I don’t show it to anyone if I feel it’s not good enough yet. I’ve learnt to listen to my partners and my friends. For me it’s the biggest success if they like it.”

The 41-year-old rocker’s work is selling for around 38,000 Euros – with the singer hoping the hefty price tag stops people from buying the pieces.

He said: “The prices are so high because I’m hoping no one will buy them.”
