Hard to comment on this on my phone at metal bar at moment, but Iron Maiden and several others you mention are legitimate, even some you didn’t agree with. I’ll be seeing Maiden in September.
Maiden has done it all: sales, influence, hard prof rock epic writing, spectacular live shows, excellent musicianship, and Bruce pilots the bloody tour aircraft.
Jann Wenner should be keelhauled.
I have a friend who was a limo driver who drove Iron Maiden around when they came to town to do a show. One of the band members liked to go jogging super early in the morning (something crazy like 4 am) and asked my friend if the downtown area where they were staying was safe for that. My friend just said “well I don’t know but I’d be careful doing that”.
