One of my first gigs was RHCP at Glasgow Green supported by Foo Fighters, QOTSA, PJ Harvey, The Distillers and Electric Six. Tickets were like £40. Insane value for money. That was 2003 though.
We've got HAIM instead of the Strokes here. I'm amazed they are playing stadiums. I'm hoping the cheap seats will be readily available on stubhub once the show actually rolls around.
