Johnny Rotten was a pivotal figure in the earliest days of Punk.  For an encore he went back to his surname of Lydon and formed Public Image Ltd who would prove to be one of the earliest purveyors of a genre that would aptly come to be known as Post Punk.   Influencing the likes of Big Black, Sonic Youth, Slint and scores of others, PiL were as ahead of their time as the Sex Pistols were and their legacy is arguably more consequential to the sound of anything that could called “alternative” music today.
