Basically i'm curious to know what exactly that is and how he is doing it. I've never really seen it done before anywhere else and i don't know if there's a particular name for it.
If anyone could help me understand it then it would be much appreciated.
Thank you (:
I'm not sure if there's a name for it, but all you do is pick the string you're playing and quickly slide you finger up a long way, then on the next higher string tap it some place low and slide it up a long way again, you can do it for as many strings as you want it just kinda sounds cool
