RHCP, along with Metallica, are basically the perfect example of what a legacy band should be. They've kept a lot of fans interested in their new music, most of their shows are still the big hits but they rotate a good amount of fan favourites over the course of a tour. I was stoked to hear Wet Sand and Me & My Friends in Vancouver, at the show after that they played Parallel Universe and Don't Forget Me, the show after that got Suck My Kiss, Blood Sugar Sex Magik and Hard To Concentrate... and so on. There's only like 4 songs that are actually staples in their setlists, but they usually find a good balance between what people at a stadium show want to hear vs what the band actually wants to play.
