Atlanta duo André 3000 and Big Boi — known together as OutKast — have announced plans for a 25th anniversary rerelease of their fourth studio album, Stankonia, set to hit stores on October 31. André 3000 created fresh artwork for the set, which drops just days before the duo's Rock & Roll Hall of Fame induction. Upon its release in 2000, Stankonia shot to second place on Billboard's Top 200. "OutKast was a great time in life, and our chemistry was at a certain place that was undeniable," André 3000 said per Rolling Stone. The first one hundred participants will get special OutKast shirts in thanks, and charity Trees Atlanta will plant 25 new trees -- one for each year since the album's release.
