The provocative promo features everything from sex to arson, and although the guitar hero is happy with the results, he admits he had some concerns when he read the original idea from director Laban Pheidias.

Slash says: "The video for World On Fire is definitely a little bit edgy. Compared to what most people are doing these days it might be a little risqu�. The actual plot line is something that you'd have to watch - it's self explanatory but pretty entertaining.

"I wanted something that was specifically dark but specifically fun. Definitely something that you couldn't play on regular TV. We interviewed a bunch of different directors and got treatments from them on the song.

"The guy who wrote and directed it had an idea we thought was cool. As long as it's not too frat-boyish, is the thing I was concerned with. When I went down to the studio to shoot my cameo he definitely had the right vibe, so I'm very happy with it."
