Neil Peart from Rush. The greatest drummer on the planet. Unless you know the song inside out, trying to predict his next move will leave you dumbfounded. Only an electronic drum machine can keep up with his rhythm, speed and stamina. Pay close attention to "YYZ" or "Red Barchetta" among many others.
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.
