Generation X popped up in London in 1979, with punksters Billy Idol and Tony James at its helm. Idol and James (who would later form Sigue Sigue Sputnik) were often criticized for embracing commercial music. Whatever the verdict, Generation X certainly pumped out smooth and pop-based sounds, especially when compared to the rebellious style of the era's punk-driven masses.
Most fans cite Gen X's first album as the best, and point to the U.S. version as the best mix of songs. The band's third and last album, Kiss Me Deadly owed much to Idol and James, who spearheaded the entire effort. Produced by Keith Forsey (the man who would later shape Idol's sound), this album featured a working version of "Dancing With Myself." That title would later bring Idol fame on his solo album.
After the band stopped producing records in 1981, Idol's pop career took off, and Sigue Sigue Sputnik earned the dubious distinction of having the first advertisement on a pop record.
