Still not getting the answer to what I'm asking...
When Depeche Mode headlined last year, I wasn't interested in seeing them, but people said they were obvious headliners because they could headline their own show at places like the Rose Bowl. Doesn't matter if I liked them or not, or they were intense: they sell tickets. Like Radiohead (who I like) and RHCP (who I don't).
The only big shows that people are mentioning for Rage are festivals and political events where they are not the main reason tickets are being sold and people are assembling.
How big were the venues that RATM played when they were headlining their own shows? It's not a criticism. Very few of my favourite bands would be big enough to headline but it doesn't mean they're not great.
