Big Gigantic teased a special guest during their set at the inaugural Shaky Beats Festival in Atlanta and sure enough welcomed out a local hero as OutKast’s Big Boi joined them for a pair of tunes including Big Boi’s own “Shutter Bug” and OutKast’s “The Way You Move.”

Big Boi most recently performed with his project Big Grams at the Hangout Festival in Alabama before heading back to Atlanta.

Meanwhile, Big Gigantic will continue their heavy festival tour with a slot at Lightning in a Bottle in California before heading back to Summercamp in Illinois.
