If they're not going to make even a reasonable attempt at making those small shows accessible to a decent amount of fans, they absolutely should put a couple "hardcore" pleasers into the arena/stadium sets. There's just no reason not to. A crowd of radio listeners isn't going to storm out in anger because they spent 4 minutes not knowing a song. How many people do we reckon actually knew The Globalist, btw? Seeing as it wasn't a single, and wasn't even available on stuff like Spotify without a premium account. They weren't shy about playing that 10+ minute monstrosity.
Anyways, plenty of other bands play a song or two for their old school crowd, and it seems to work out pretty well for them.
