What are the chances that they'd play a regular LA show?

I hear there's some Coachella rule about big-money headliners announcing surrounding-date shows (before festival sells out...?), but many/most do.

And I'm not fond of festivals (traumatic childhood experience, doncha know). But might risk additional therapy to see Blur...in the dusty heat, with a gazillion sweaty, stinky... nah, fuck no...

But I do really want to see Blur. What're the odds they'll do a one-off in LA?
