“Being a madman is good thing!” Perry told Rolling Stone reporter in 2010. “It keeps people away. When they think you are crazy, they don’t come around and take your energy, making you weak.” Under the guise of the court jester, Perry infiltrated Western music, earning that nickname of “the Upsetter” as he set profound messages to enticing grooves. As a forefather of dub reggae, he upended just what a song could contain, what elements it needed to be successful in the dancehall. Other musicians understood Perry’s vision and gravitated toward him, with the likes of the Rolling Stones, the Clash, Kanye West, Madlib, Robert Palmer, Sublime, Carl Craig, the Beastie Boys, Basic Channel and more — either in-person, in spirit, or via sampler — carrying his sound forward.
