Generation X (also known as Gen X) originally formed in 1976 in London, England by three ex-Chelsea members. They played their first gig on 21 December 1976 at Roxy club (becoming one of the very first punk bands to play at the venue). They were one of the first punk bands to play at BBC music programme Top Of The Pops.
Unlike the other punk bands, they ignored some of the "rules" and "ideals" adopted by UK punk bands, taking inspiration of British pop of the 60's.
Their singer Billy Idol is better known from his later pop period.
