Thanks Case, I will check him out. That was the real point of the original question, not so much the musician who is greatest at playing one instrument, because then it is a matter of the listener's taste in music and instruments. When someone is truly prodigious at two or more instruments, that is what freaks me out. Especially when the instruments are as divergent as forms of expression in a physical/technical sense, such as drums versus violin, etc.
Best musician in the world?
A question posed in another thread, in my view, although musicianship is hardly a sport to be measured as such, the most universally prodigious musician is probably Shawn Lane. He is definitely the world's most phenomenal/inimitable electric guitarist. And he is a world-class pianist and saxaphonist as well.
