Slash and Myles Kennedy graced the stage of 'Conan' on TBS last night (Sept. 26). The duo jammed the new song 'Nothing Left to Fear,' which is the title track to a horror film produced and scored by the mad hatter himself.

On Oct. 4, both the 'Nothing Left to Fear' film and its official soundtrack will see the darkness of a movie theater and the light of day, respectively. 'Nothing Left to Fear' is Slash's inaugural motion picture endeavor and is actually being put out by the guitarist's own production company, Slasher Films. It's also his first foray into film scoring, which artists such as Trent Reznor have found a great deal of prosperity in. Along with Slash's writing partner Nick O'Toole, the guitarist wrote the flick's entire score along with the two original tracks, 'Nothing Left to Fear' and 'Welcome to Stull.'

Slash and Myles Kennedy performed the film's haunting title track on 'Conan,' cutting the seven-minute track down to about four-and-a-half minutes for the show. Kennedy, who also manned an acoustic guitar for the gig, delivers a truly mesmerizing vocal offering. The Alter Bridge vocalist truly makes the song come to life, and the footage of the duo's 'Nothing Left to Fear' performance will surely cause your skin to crawl.

Watch Slash and Myles Kennedy performing 'Nothing Left to Fear' on 'Conan' in the video above, and be sure to check out Slash's 'Nothing Left to Fear' film, which will hit select theaters on Oct. 4. To grab a copy of the movie's soundtrack, which also comes out on Oct. 4, head over to Pledge Music.
