the sex pistols were the first popular punk group in britain and one of the first bands to come from the rising u.k. punk scene of the late 1970s. they were only together for about 3 years, from late 1975 to early 1978, and they were known for their rowdy behaviour more than their music. the music they made gave many new artists a big influence on their music, mostly in the alternative music and punk scenes such as california punk rock group green day.
