I first saw Jason Mraz at a small venue in Austin (Paramount) a few years ago. He was just starting to become a name in the music scene, so I barely knew his music. The show he put on that night was truly amazing. He was a great singer, could rap, told great stories and played a whole variety of muscial instruments. He basically showed just how much talent that he has.
We saw Jason Mraz again in 2009 at the Frank Erwin Center in Austin. This time he was playing a large venue, but the show felt similar in that he controlled the crowd. He was singing, rapping and joking around just like he had years before. Clearly success has not gone to Jason Mraz's head because he puts a ton of effort into his live show and the audience benefits from it. I would highly recommend seeing Jason Mraz in concert, he's one of the best.
