Jason Mraz + Christina Perri

Well-behaved singer-songsmith Jason Mraz, with an appeal to fans of David Gray or those who think Jack Johnson's gotten a bit too edgy in his old age, plays a pair of big area gigs. The fedora-clad San Diegan is playing behind his latest, Love Is a Four Letter Word. Husky-voiced "Jar of Hearts" songstress Christina Perri, who got her big break performing on So You Think You Can Dance, supports with her emoto-pop.
