paragraph_text: Music and dance
  
  Irish traditional music has remained vibrant, despite globalising cultural forces, and retains many traditional aspects. It has influenced various music genres, such as American country and roots music, and to some extent modern rock. It has occasionally been blended with styles such as rock and roll and punk rock. Ireland has also produced many internationally known artists in other genres, such as rock, pop, jazz, and blues. Ireland's best selling musical act is the rock band U2, who have sold 170 million copies of their albums worldwide since their formation in 1976.
  
  There are a number of classical music ensembles around the country, such as the RTÉ Performing Groups. Ireland also has two opera organisations: Irish National Opera in Dublin, and the annual Wexford Opera Festival, which promotes lesser-known operas, takes place during October and November.
  
  Ireland has participated in the Eurovision Song Contest since 1965. Its first win was in 1970, when Dana won with All Kinds of Everything. It has subsequently won the competition six more times, the highest number of wins by any competing country. The phenomenon Riverdance originated as an interval performance during the 1994 contest.
  
  Irish dance can broadly be divided into social dance and performance dance. Irish social dance can be divided into céilí and set dancing. Irish set dances are quadrilles, danced by 4 couples arranged in a square, while céilí dances are danced by varied formations of couples of 2 to 16 people. There are also many stylistic differences between these two forms. Irish social dance is a living tradition, and variations in particular dances are found across the country. In some places dances are deliberately modified and new dances are choreographed. Performance dance is traditionally referred to as stepdance. Irish stepdance, popularised by the show Riverdance, is notable for its rapid leg movements, with the body and arms being kept largely stationary. The solo stepdance is generally characterised by a controlled but not rigid upper body, straight arms, and quick, precise movements of the feet. The solo dances can either be in "soft shoe" or "hard shoe".
