Where does the “Biffy were due to sub Reading this year” thing come from? Was there ever any suggestion they would play Reading/Leeds?
QOTSA are headlining Victorious this year and also headlined Download so I don’t think it would drop Biffy out if headline contention.
Biffy will never be top of the list but if Download are struggling for headliners (as they have done in recent years) and Biffy are in an album cycle they will get the call.
