Justin Timberlake and The Killers are to headline this year's V Festival.
Other big name acts lined up over the weekend for the twin-site event include Ed Sheeran, Paolo Nutini, Lily Allen and Elbow.
Crowd-pleasing star Nile Rodgers will also be performing with his disco act Chic at the festival, staged at Hylands Park, Chelmsford, and Weston Park, Staffordshire, on August 16 and 17.
Brit Award winners Bastille, Sam Smith and Rudimental will be playing, and Katy B - who recently topped the album chart - is on the bill.
In addition, the line-up will include Example, Kaiser Chiefs, Manic Street Preachers, The Human League and All Saints among the dozens of performers who will play on four stages across each site.
Tickets go on sale on Friday from 9am at www.vfestival.com. Around 170,000 people will attend across the two days with the acts alternating at each location.
V Festival director Bob Angus said: "We have pulled together a line-up of huge depth with a variety of artists across many musical genres and 2014 is set to be another fantastic year in V Festival's 19-year history."
