Giovanni Mazza is just like any other teenager when it comes to school and homework. But the rest of the time, he’s practicing violin or traveling the country to play at NBA games. “I get kind of nervous right before I start, but then once the music starts, I’m fine and I just have fun,” he told InsideEdition.com. It’s not a classical performance he’s wowing the crowds with. Instead he’s playing hip-hop. InsideEdition.com’s Leigh Scheps (http://twitter.com/LeighTVReporter) shares his story.
