Pendulum will headline this year's High Definition Festival.

The drum and bass group - who said last year that they were going to take 2012 off and return in 2013 - are to be joined at the electronic extravaganza by Mercury-winning artist Ms. Dynamite, Sub Focus, Fabio and Radio 1 DJ Mista Jam.

Festival Director, Daniel May, said: ''We were blown away by the response to last year's event and can't wait to get 2012 under way. We've got an obsessive passion for what we do. It's about attention to detail: the artists, the sound, the visuals, the quality of the experience.

''This is by enthusiasts for enthusiasts with some of the best names in electronic music. This year is going to be special.''

The festival - which is taking place on Saturday June 30 at Forest Farm in Essex - will feature five specialist stages and a number of food, entertainment and VIP areas.

Tickets are now on sale for the spectacle, with a strict limited number of early bird tickets available at £25, with standard tickets following at £40 and VIP tickets at £75.
