OTTAWA - Nickelback, K'naan and Norah Jones are among the artists who will be on the bill for this year's Ottawa Bluesfest.

John Mellencamp, LMFAO, Snoop Dogg, Skrillex and Iron Maiden are also among the scheduled performers at the festival, which runs July 4 to July 15.

Other Canadian artists confirmed for the festival include Blue Rodeo, the Sheepdogs, Metric, Grimes and City and Colour.

Tickets go on sale on Saturday.

Last year's festival ended on a down note, when Cheap Trick's performance was cut short after scaffolding buckled during a violent summer storm.

Four people were hurt, including the group's truck driver.
