"The concept began among the musicians in the communities of San Francisco and San Diego," Mraz explains. "I look forward to it being a great experience for the audience and performers alike. It will feature a variety of talent not unlike the vaudeville format where different musical genres, magic, poetry, and educational themes will come together in one night."

Pre-sale tickets for a number of shows � including stops in San Francisco, West Hollywood, Philadelphia, New Orleans, Atlanta, and New York � will be available for members of Jason's online and mobile fan club on March 18th. All remaining dates are on sale now.
