Petter is one of the most-known artists and songwriters in Sweden. He is now in the middle of celebrating 20 years as an artist. He is also a sommelier and engaged in restaurants.

For his interpretation of the Knotted Gun sculpture he used an oil painting of a man walking through a desolate subway aisle. The text is from the song “Tårar” (“Tears”) that he made together with the artist Feven.
