In the following clip from Disney's Phineas and Ferb: Across The 2nd Dimension, (courtesy of RollingStone.com) former GUNS N' ROSES and VELVET REVOLVER guitarist SLASH flips a switch on his amp that turns him into a cartoon character. Upon entering the animated zone, he jams out with the show's protagonists on a tune called 'Kick It Up A Notch' before a huge stadium crowd. To catch the full song, tune in to the tv movie when it premieres at 8pm on the Disney Channel on Friday, August 5th.

'Kick It Up A Notch' is currently available for streaming at this location.

Slash previously stated: "I co-wrote and performed a song for my guilty pleasure, Phineas And Ferb recently. Its coming out in August. Very R&R.; Even for a cartoon! Its actually a song for the new feature length Phineas And Ferb movie. I will be in the animated video to launch the movie as well. Pretty cool."
