Great footage, I might actually buy this. Quite some overplaying on MP's side though.
And damn, it's amazing that Steve can play that well with such av whacky picking technique!
It has been his trademark for years and years. He has a pretty good explanation for it too.
"I hold the pick with thumb and two fingers, with my heel normally resting on the bridge, which allows me to easily cover any unplayed strings with my extended RH 5th finger, or the heel of my RH. This is not the fastest way, for sure. What it does for me is to give me a lot of control, and the ability to easily jump strings, which I love to do. Fastest, for sure, is the traditional, more whip-like floating right hand pick position. I've noticed that my son, who uses a more traditional position can easily outspeed me, but has a little bit more of a challenge to play some parts of mine, such as the intro to "Tumeni Notes". However, it's interesting to me that since he does some parts that jump strings at an early stage, that it may turn out to be the best of both worlds: speed of traditional, but learning untraditional patterns. Remember, though, that a floating right hand (traditional) will never be able to control and mute as well, but will probably give you more speed and endurance."
