For the Welwyn & Hatfield Times has teamed up with the organisers of the Sonisphere Festival to offer 20 tickets to the event.

Four lucky winners of our super Sonisphere competition will win a weekend ticket to the festival for themselves, plus four more for their friends.

That's five tickets in total worth more than �500!

The two-day event will be headlined by Linkin Park on the Saturday with Metallica closing proceedings the following night.

Festival director Stuart Galbraith said: "Sonisphere will be 50,000 people camping and the best rock music in the world."

Explaining the ethos behind the event, he added: "The idea of the festival is to have rock in its broadest sense.

"We've got everything from Heaven & Hell and Saxon on the classic side to more accessible radio-friendly acts like

Taking Back Sunday, Feeder and Linkin Park and hardcore with Metallica and Anthrax, and industrial with bands such as Killing Joke and Nine Inch Nails."

To stand a chance of winning, all you have to do is answer the following simple question.
