Always the innovator, Lee "Scratch" Perry turned not to any of his fellow reggae producers for help on his new album, Repentance, but to Andrew W.K. The reggae icon and producer with something of a frat boy following met at SXSW in 2006, and, as the story goes, an unlikely partnership was born, resulting in Andrew W.K. co-producing the new album. Repentance will drop on August 19, but to gear fans up, Perry released the sexually charged single, "Pum Pum," which is currently getting the blog world all hot and bothered. The track's accompanying video should only add more fuel to the fire.
