Η Αγγλική έκδοση του Sonisphere Festival δεν θα πραγματοποιηθεί τελικά το 2013, ένα φεστιβάλ που στις υπόλοιπες χώρες οι Iron Maiden είναι headline. Η δήλωση από τους διοργανωτές έχει ως εξής: Τα τρία φεστιβάλ Sonisphere μέχρι σήμερα στο Knebworth το 2009/2010/2011 είχαν πολύ υψηλό επίπεδο και μάλιστα το 2011 βραβεύτηκε ως το καλύτερο line up φεστιβάλ από τα βρετανικά βραβεία φεστιβάλ.
We think it is really important that the event only runs when it has a
lineup that sets it apart from the competition whilst also carrying a
ticket price that allows us to offer real value for money to the music
fans. We were hoping to do that in 2013 but unfortunately it wasn't
possible to fulfil both aims with the principle problem of there being a
lack of available headliners of the calibre of previous festivals at
Knebworth. We made offers to over a dozen major artists but for various
reasons none of these offers lead to securing a strong bill. The good
news is that the Sonispheres in Amneville, France and Milan,
Italy are already on sale and UK fans who fancy jumping on a budget
airline and seeing the mighty IRON MAIDEN at Sonisphere festivals in sunnier climates can buy tickets via SonisphereFestivals.com in pounds sterling."
