I Can't Stop Thinking About that Youtube Video
I've watched the video I linked to above here several times now. There is a whole study out of how this guy plays. And I think if any 2 mallet player incorporated that into his playing he opens up a whole new world of things.
Since the instrument is pentatonic I realize there's a sort of drum factor happening there, but still that guy makes so much music out of that instrument, I'm floored.
