I was just curious on what technique he is using, on the tones after the high C.
I`m playing in a blues band and tests differents techniques on the high tones after double C:
An usual evening with the band for me is playing 3X 45 minutes, and half of the evening from double Bb and up, so I`m curious in other technigues .
