GRAMMY winner 'Wizard' Jason Mraz is planning a magical show in Shanghai next week - his first concert in the city.The performance at Shanghai Grand Stage on June 14 is part of Mraz's world tour - 'Tour Is a Four Letter Word' - celebrating his new album 'Love is a Four Letter Word.' Beijing and Shanghai are the only two stops on the Chinese mainland. Mraz promises fans that he will perform his hits, though saying he might also try out new material.'I always like to test new songs on tour,' says Mraz. 'I haven't decided which songs to test yet. We'll see. But definitely, I'll play some of the hits like 'I'm Yours' and 'Lucky'.'Since this is Mraz's first visit to Shanghai, he is unsure what to expect, but is ready to be surprised by the city and the audience here.Starting as a coffee shop singer, where he picked up his Wizard nickname, Mraz brings his own magic to live performances, in most cases just with his guitar and voice.
