Just saw an instructional video by Greg Howe, and I was quite impressed with the technique he uses.
He calls it “Hammer-Ons From Nowhere”, and what a cool concept.
I guess he is building a lesson workshop website that he’s plans on releasing in the summer at www.ghworkshops.com.
Be sure to check out his instructional video, as well as some of his songs where he uses the technique- such as “A Delicacy”.
My friend sent me a link today to a YouTube video of a person named Michael Angelo Batio playing a double necked guitar solo. This is one of the most creative guitar feats I have witnessed yet. To play as a right handed person while being left handed that fast has to count for something. He then goes to a cross armed tapping solo with each hand on opposite guitar necks. The level of performance this guy plays at is simply incredible. A great showman (some say too much), and a very technical and fast guitarist. Read an interview he has with Ultimate-Guitar here, as well as this sweet video, along with some of his other works.
