Run-DMC are set to reunite for the first time in over a decade to perform at the Fun Fun Fun Fest in Austin, Texas.
Joseph Simmons, now known as Rev Run, and Darryl "DMC" McDaniels retired the group after their DJ, Jam Master Jay, was killed in 2002.
But it has now been announced that the band will be among the performers for the November 2-4 event.
Festival organisers say they plan to donate some of the proceeds to the JMJ Foundation for Music, which works to give youth access to the arts.
The Rock and Roll Hall of Fame group are best known for their hits Walk This Way and It's Like That.
