Dental issues have forced Solange Knowles to pull out of her planned performance at Outkast's ATLast festival in Atlanta, Georgia this weekend (26-28Sep14).

Beyonce's sister was billed to hit the stage on Friday night (26Sep14) alongside the funk duo, Janelle Monae and 2 Chainz, but she has pulled the plug on her set due to "complications arising from a recent root canal".

Her slot on the bill will be filled by rapper Future.

The three-day Centennial Olympic Park festival will also feature performances from Kid Cudi, Childish Gambino, B.o.B, Killer Mike, and Bun B.

Outkast's Big Boi and Andre 3000 will appear every night.
