I used to listen to recordings of Joe Satriani playing his Strat years ago; he’s yet another guitar virtuoso. Today I happened across this video:
I’ve had a musical problem in the past — if I listen too often to players much better than I am, I become discouraged and don’t play much. It’s better if I just play as well as I can!
I wondered about why Satriani was wearing a stocking cap during several videos during this time-period, presumably in a well-heated auditorium. I suspected the advent of male pattern-baldness. In videos from subsequent years the guitarist had shaved his head, more-or-less confirming my hypothesis.
