While the Sex Pistols instantly changed the face of rock ‘n' roll in 1977, John Lydon's post-Pistols outfit, Public Image Ltd., has arguably been just as influential. Their visionary fusion of dub-reggae grooves and post-punk guitar squall would spawn genre-bending contemporaries The Pop Group and Liquid Liquid, mid-'80s industrial acts like Skinny Puppy and Meat Beat Manifesto, the '90s trip-hop of Portishead and Massive Attack, and post-millennial death-disco revivalists The Rapture and LCD Soundsystem. That's quite a legacy for guy who once snarled, “no future.”
