For me, RHCP, at least in the concerts I have been to.

First one was in Rock in Rio 2019. Kiedis forgot the lyrics, so he was just crouching and reading them thru a paper time to time(no teleprompter for some reason). Kinda takes away from the experience. Kiedis admitted back then he had a hard time remembering the lyrics though.

Also last year in Germany, my first time seeing Frusciante live, he just stood at the corner playing. I mean I get it, not every guitarist need to have stage presence or look cool(Slash, Joe Perry, etc) but at least try to look like you want to be there. Frusciante looks bored and hardly go to the center of the stage.

Kiedis voice was meh live as well. It was Flea who is the saving grace of a RHCP concert.
