Returning to the stage for their 20th anniversary: Outkast headlines Summerfest Sunday

MILWAUKEE (WITI) -- Headlining the Marcus Amphitheater at Summerfest on Sunday, June 29th -- Outkast, with special guest Gary Clark Jr.

Ingenious and iconic recording artists and performers, Antwan “Big Boi” Patton and André "3000" Benjamin announced via Outkast’s newly launched social media platforms, their return to the stage for their 20th anniversary will include festival dates around the world.

The influential group will be the marquee act at over 40 festivals around the world throughout the Spring/Summer of 2014.

To sum up Gary Clark Jr. is more challenging every day.

He’s a musical universe unto himself, expanding at a nearly immeasurable rate, ever more hard to define — as a mind-blowing guitarist, a dazzling songwriter and engagingly soulful singer.

With his debut album Blak And Blu, he has become the first artist ever recognized by the Recording Academy with Grammy Award nominations in both the rock and R&B categories for the same album in the same year, winning the latter: “Best Traditional R&B Performance” - “Please Come Home”.

It’s a lot to live up to, but through it all his musical ambition and reach continue to grow.

New songs he’s previewed to delighted audiences show him exploring ever further combinations of sounds and styles, all with his distinct stamp.
