Known for his inspirational messages and smooth, cheery voice, Jason Mraz is a singer-songwriter, social activist, and philanthropist who has been uplifting audiences around the world since his debut in 2002. Now touring behind the release of his tenth album, "Know," Mraz is joined by gifted percussionist-singer Noel "Toca" Rivera. While Mraz sings sweet melodies over his acoustic guitar, Rivera counterbalances with Latin-infused rhythms and soaring backing harmonies. Mraz and Rivera create soulful pop music together, playing off the immensity of each other's talents and having a blast the entire time.

Jason Mraz and Toca Rivera will perform, along with opener Gregory Page, on Saturday, December 1, 8 p.m. at Auditorium Theatre, 885 East Main Street. $39-$85. 222-5000. rbtl.org; jasonmraz.com
