Phil must have been a very good drummer that did his things with a lot of strength to have incurred such illness. Oh yeah, drumming demand a lot of body movement in a fast manner depending on the kind of song being played.
I used to drum... but not a pro😅
Musicians need to take care of themselves. Bad posture can cause problems later. It may look good to have the cymbals up high, but it means a lot of bad stretching.
I will never be a pro, but it's fun.
Oh yeah, I grasp. Bad positioning sure has a way of suffering the body
