The former Guns N' Roses guitarist will appear in a film adaptation of the popular Disney Channel cartoon Phineas and Ferb.
After flicking the switch on his amp, Slash turns into a cartoon character and performs a new track titled 'Kick It Up A Notch' with the film's lead protagonists.
The full song will debut in full during the film Phineas and Ferb: Across the 2nd Dimension, which will air on the Disney Channel in the US on August 5.
Earlier this year Slash admitted that he would consider a future reunion with Guns N' Roses, after leaving the group back in 1996.
