Agreed - dress up, not three piece suit, but something appropriate for a live performance.The only rule I have, is don't dress like dad on a beach holiday. Sandals, Bahamas shirts and cargo shorts look dorky onstage, IMO. No one wants to see middle aged men's chubby hairy legs and feet for a 2 hr set. Yet lots of bar bands dress this way.
LOL Worked briefly with these guys, doing a video shoot in a production studio I worked at 26 years ago. Man, they left a mess when they were done (but surprisingly nice guys, all things considered). They gave Billy, the editor, a really nice latex squashed cat that he forever after placed on his online monitor (this was the CRT era, you could do that) while he was working, as if to say "Bill's in the house, don't f$%k with my shit."
