The people who have not listened to any new music since 2006 are gonna scream the place down on social media - But at some point they will just have to try something new.
Glastonbury spent the last 15 or so years ticking off every big legendary headliner they could and have basically gone through the entire A tier (who were willing to do it) and are now resorting to the B tier. Obviously still able of pulling something huge like Elton or Coldplay on an exclusive, but it’s less of a given than it was a few years back for sure.
