Meanwhile, Scotland's RockNess festival has decided to suspend its 2014 edition and gear up for 2015

Outkast are headlining yet another festival, and it's Ireland's Electric Picnic. Beck and Portishead are listed as the other headliners and remarkably, the latter are actually listed ahead of Outkast on the official poster, showing just how popular the trip-hop group remains in the United Kingdom.

Other prominent acts include Lily Allen, Pet Shop Boys, Chic (featuring Nile Rodgers), London Grammar, St. Vincent, and Billboard 2014 artists to watch FKA Twigs and Sohn. The current lineup is listed here, though the poster assures many more will be announced.

Outkast Announce Tour of Over 40 Festivals

Electric Picnic is set for Aug. 29-31 at Stradbally Estate in County Laois, Ireland. Tickets are available here.

The Irish music fest has been running since 2004. Last year's lineup included Björk, Arctic Monkeys, Disclosure, My Bloody Valentine, Wu Tang Clan and many others.

In other regional music festival news, Scotland's RockNess festival has announced plans to cancel its 2014 showing. "Due to the addition of a number of events alongside the World Cup and the Commonwealth Games we’ve decided to take a year off," the festival announced via its official Facebook page. "We’re using this break to make the event bigger and better than ever in 2015 so have an amazing summer and see you back at the Loch next year!"
