Watching people do what they do best is always a gratifying experience. Whether you're in the presence of an expert orator who can bring an entire audience to its feet or you're in the crowd cheering for a star athlete, it's always cool to see someone in their element.
And there's something uniquely wonderful about watching musicians at work. When it comes to making us jealous, these virtuosos know exactly how it's done. If you thought pianists and violinists were enviable, wait until you see what this guy can do.
