Tech in metal??
wow never thought of it,Technique yes but not a machine doing something.
maybe we are looking at it from the wrong end,maybe it is not the musical aspect that will or even has to change./suppose it is us that change,perhaps we are marching toward another plane,a higher plane of listening.
could we be headed into feeling the music directly to the brain instead of hearing it??
who is to say or possibly know.
one thing is sure there will always be a body slamming the drums,a body hammering the bass,fingers doing gymnastics on a fretboard and Vox doing it some sort of way,,,,,,
