Avicii, Tinie Tempah, Rudimental and Tommy Trash have been announced to play at a third day of Tennent's Vital on Friday, August 16.
The 2013 festival at Belfast’s Boucher Road Playing Fields will be the biggest yet, with the party continuing over three days.
Organisers Tennent’s Lager and MCD have also revealed that top festival act The Vaccines have joined the bill for Day One, on Wednesday, August 14.
Swedish dance megastar Avicii is one of the most in demand DJs and producers in the world, and will headline the third day of Tennent’s Vital.
After making a big impression with hit single Seek Bromance in 2010 and his 2011 collaboration with David Guetta Sunshine, he was catapulted to global stardom by the Grammy nominated, multi-platinum selling Levels, which dominated airwaves and dancefloors across the globe in 2012.
Ranked No. 3 in the world’s top 100 DJs by dance bible DJ Magazine, he made history by becoming the first DJ to headline New York’s prestigious Radio City Music Hall, with tickets for one of the two sold-out shows snapped up in under a minute.
Tinie Tempah is one of the biggest stars to emerge from the UK grime scene in recent times.
His massive no.1 debut album Disc-Overy took the world by storm, spawning the smash hit singles Frisky, Miami 2 Ibiza, and the chart-topping Written in the Stars and Pass Out.
Also joining this year’s ultra-impressive Tennent’s Vital line-up are drum and bass stars Rudimental.
The London four-piece rocketed to fame when their single Feel the Love topped the UK singles chart, before going on to become a multi-platinum smash hit success and earning them BRIT Award nomination for Best British Single.
At the start of 2013 they returned to the number 1 spot with Waiting All Night, swiftly following up with a number 1 debut album.
With a plethora of his own carefully created anthems, Grammy-nominated Tommy Trash is also hugely in demand as a producer, having remixed for the likes of Swedish House Mafia, Deadmau5, Steve Aoki and Zedd.
With a repertoire packed full of feel-good festival anthems, The Vaccines’ high octane tunes are sure to go down a storm when they join Kings of Leon on the bill for Day One.
Rising to the top in 2011 with their phenomenal top-five debut album What Did You Expect from The Vaccines? the band then went on to win the Best New Band award at the NME Awards in 2012 and score a number 1 album with their second record Come of Age.
