In the Spring of 2002, one of the most unlikely rock crossover events in history took place as puerile Canadian pop punk heroes Sum 41 managed to somehow wing a guest appearance on one of their tracks from a revered thrash metal icon. The song in question, titled What We're All About and reworked from one of the band's older cuts, was recorded for the soundtrack of that year's blockbuster, Sam Raimi-directed Spider-Man movie.
A goofy rap-rock bop that owed more than a little to the Beastie Boys, the song's video featured clips of Spider-Man spliced in with shots of Sum 41 playing a gig on a ceiling as their jubilant fans watch from below. Just under two minutes in, however, viewers were greeted with an almighty shock: Slayer guitarist Kerry King striding into shot and nailing a solo as the song suddenly lurches into galloping heavy metal.
