Outkast celebrated its 20th anniversary with a reunion tour, making Austin City Limits Festival one of the duo's final stops.

Austin was one of 40 festival stops the Atlanta-based duo made this summer, with one of the highlights being when they sang "Deep in the Heart of Texas."

"Texas has always been a major part of our career," said Andre 3000 before they launched into the Lone Star anthem. After singing "The stars at night are big and bright," before letting the crowd finish with "Deep in the heart of Texas," Big Boi said "I always wanted to do that s*$&t. And all my exes live in Texas. For real."

The duo wowed the massive Texas crowd with all the hits from their decades-long career, opening with B.O.B., and playing fan favorites like ATLiens; Rosa Parks; Aqeumini; Ms. Jackson; The Way You Move; Hey Ya!; Roses; So Fresh, So Clean; and closing with The Whole World.
