The two Canadian artists will alternate closing duties on the 22-city trek, which marks their first tour together.

“I’ve loved these crazy gentlemen for years, and it will be a true honor traveling around America making some joyful noise with them,” Morissette said. “I look forward to being with a group of people who will not snicker to themselves when I say the word ‘about’ or ‘eh’ … making art and cracking up on tour with the Barenaked Ladies sounds like a fantasy summer to me.”

“As musicians we’ve had great admiration for Alanis,” the Ladies’ Steven Page added. “She’s not afraid to speak her mind, and neither are we, so fans should expect a terrific balance of poignant fun during the course of the evening!”

Morissette’s new album, So-Called Chaos, comes out May 18, and Barenaked Ladies are supporting last year’s Everything To Everyone.
