Jason Mraz and Contemporary Youth Orchestra

Known for hits such as "I'm Yours" and "I Won't Give Up," singer-songwriter Jason Mraz has sold out venues such as the Hollywood Bowl, Madison Square Garden and London's 02 Arena. One thing he hasn't done is perform with an orchestra. This week, however, he'll change that as he comes to town to play with the 115-piece Contemporary Youth Orchestra. Concerts take place at 7 tonight and at 4 p.m. tomorrow at Severance Hall. Check the Cleveland Orchestra website for ticket info. (Niesel)
