Pop music legend Stevie Wonder will be the headline act at the 30th Montreal International Jazz Festival this summer - and his concert will be free.

The outdoor extravaganza will be held on June 30.

Wonder will be the first artist to play at the newly-configured downtown festival section.

Wonder, 58, last played Montreal in 2007.

He is considered one of the greats of music, with a 50-year career that spans the rock, Motown, soul and hip-hop eras.
