Some people say drummers can hide behind their kits, that it’s the safest place to be on stage but I don’t think a person can get much more exposed than when they’re drumming because all of them is engaged in the business. You can’t drum sitting still.
Drumming is a whole-body symphony of movement. When a good drummer is on form there is nothing left of them but beat-by-beat motion. Rhythm is the spine of music and like all good art requires at least a momentary sacrifice of self.
