After sharpening his performance teeth on stage appearances in theatres, Peter and a few friends soon turned to music. He fronted several local bands like Disobedient, Soultaker, Uncle Meat/Toner.
In 2003, Peter came out on top in the first Belgian edition of Idols and the result of this was his first official solo single, which entered the charts at number one. This landmark achievement was the first for a Belgium artist.
After the nationwide search for Belgium's Idol, Peter went on to represent his country at the world-acclaimed International Idols where he reached third place during the final round.
