Rock music has been a part of the music of Ireland since the 1960s, when the British Invasion brought British blues, psychedelic rock and other styles to the island. The Irish music scene in the 1960s and much of the 1970s was dominated by the unique Irish phenomenon of the 'Showbands' which were groups of professional performers who played at dancehalls and clubs across the country putting on a professional 'show' and playing all the American and British hits of the era.
