Perhaps this is a lesson in ergonomics.
Phil Collins was the drummer for Genesis, and when Peter Gabriel left, he took over the singing duties, but he always saw himself as a drummer first.
But no more. Due to spinal injury, he's giving up the drums. Evidently, it's hooked to how he sits on the drum throne.
I've never really looked into ergonomics, especially the ergonomics of guitar. I know that I used to sit at an ergonomic desk with a keyboard extender that sat below my knees. That desk actually hurt me until I took off the keyboard extender.
Anyway, I always liked a bunch of his work. Sad to see him leaving the drum kit.
