Rumours were rife over the past week, but we can now confirm the unbelievable news that Sonisphere 2012 has been cancelled. Although reported to be down to poor tickets sales, the organisers official statement doesn't actually pinpoint a reason. The full statement reads:

"It is with very heavy hearts and much regret that we announce the cancellation of Sonisphere Knebworth 2012.

"Putting the festival together in what is proving to be a very challenging year was more difficult than we anticipated and we have spent the last few months fighting hard to keep Sonisphere in the calendar. Unfortunately circumstances have dictated that we would be unable to run the festival to a standard that both the artists and that Sonisphere’s audience would rightly expect.

"We want to express our deepest regrets to the artists and to thank all the staff, suppliers and contractors who worked so hard with us to try and pull off what has proven to be an impossible task and we know how much they share in our disappointment. We also want to send a huge thanks to the Sonisphere fans who stuck by us and we are so sorry that we can’t fulfil what we set out to do."

Why tickets weren't selling aren't clear, but with headline acts such as Kiss, Faith No More and Queen (featuring Adam Lambert on vocals) it would seem that it was a lack of appetite for nostalgia on the part of fans rather than anything indicative of the festival itself which has, in the past, enjoyed a lot of success and expanded to several other sites across Europe. Tickets will be refunded by the agents who sold them to customers.
