OutKast is celebrating 20 years in music in a major way.

The rap duo will headline more than 40 music festival dates around the globe this spring and summer, the Atlanta rappers announced via their official website Monday (Jan. 13).  

As previously reported, Big Boi and Andre 3000 will lead this year's Coachella Music and Arts Festival launching April 11 over two consecutive weekends, followed by the Governors Ball, kicking off at New York's Randall's Island in June.

Additional show dates have yet to be announced.

"It's truly an honor to celebrate 20 years and still be free to do musk the way we choose," Big Boi said in an statement on the OutKast website. "Don't just think outside the box, know that there is no box. I'm looking forward to rocking the stage with my Bro Ski and to all the fans — stank you smelly much, this is for ya'll!"

Added Three Stacks, "And imagine all we wanted to do was rap! I am thankful to have been a part of a group that allowed me to explore anything that came to mind and have fun doing it. Returning to the stage together is the most exciting way for us to thank everyone for their 20 years of supporting OutKast."

Given the number of tour dates, OutKast could be preparing fans for a new album, but have not unveiled plans to do so. The Grammy-winning rap star's Southernplayalisticadillacmuzik debut was released in April 1994, while their last studio album, Speakerboxx/ The Love Below dropped over a decade ago.
