This July, Knebworth will once again rock to the sounds of Sonisphere, with the festival back once again, and looking very nice, thank you very much!

The first two headliners are Metallica and Iron Maiden who will each headline one of the three nights, from Friday 4th to Sunday 6th July. And, as an extra special treat, Metallica are running a scheme whereby fans with tickets can customise the set! Ticket-holders will receive a code allowing them to vote for their favourite Metallica track. The top songs voted for will be the ones played on the night.

Limited early-bird tickets are now on sale, costing £205 for weekend camping, £170 for the weekend without camping with other options available.
