Irish folk music in the context of "W. H. Grattan Flood"

Throughout the history of the British Isles, the land that is now the United Kingdom has been a major music producer, drawing inspiration from church music and traditional folk music, using instruments from England, Scotland, Northern Ireland, and Wales. Each of the four countries of the United Kingdom has its own diverse and distinctive folk music forms, which flourished until the era of industrialisation when they began to be replaced by new forms of popular music, including music hall and brass bands. Many British musicians have influenced modern music on a global scale, and the UK has one of the world's largest music industries. English, Scottish, Irish, and Welsh folk music as well as other British styles of music heavily influenced American music such as American folk music, American march music, old-time, ragtime, blues, country, and bluegrass. The UK has birthed many popular music genres such as beat music, psychedelic music, progressive rock/pop, heavy metal, new wave, industrial music, and drum 'n' bass.

In the 20th century, influences from the music of the United States, including blues, jazz, and rock and roll, were adopted in the United Kingdom. The "British Invasion"—spearheaded by Liverpool band the Beatles, often regarded as the most influential band of all time—saw British rock bands become highly influential around the world in the 1960s and 1970s. Pop music, a term which originated in Britain in the mid-1950s as a description for "rock and roll and the new youth music styles that it influenced", was developed by British artists like Black Sabbath, the Beatles and the Rolling Stones, whom among other British musicians led rock and roll's transition into rock music.

Thin Lizzy are an Irish rock band formed in Dublin in 1969. The band initially consisted of bass guitarist, lead vocalist and principal songwriter Phil Lynott, drummer Brian Downey, guitarist Eric Bell and organist Eric Wrixon, although Wrixon left after a few months. Bell left at the end of 1973 and was briefly replaced by Gary Moore, who himself was replaced in mid-1974 by twin lead guitarists: Scott Gorham, who remained with the band until their break-up in 1983, and Brian Robertson, who remained with the band until 1978 when Moore re-joined. Moore left a second time and was replaced by Snowy White in 1980, who was himself replaced by John Sykes in 1982. The line-up was augmented by keyboardist Darren Wharton in 1980.

The singles "Whiskey in the Jar" (1972), "The Boys Are Back in Town" (1976) and "Waiting for an Alibi" (1979) were international hits, and several Thin Lizzy albums reached the top ten in the UK. The band's music reflects a wide range of influences including blues, soul music, psychedelic rock, and traditional Irish folk music, but is generally classified as hard rock or sometimes heavy metal. Lynott led the group throughout their fourteen-year recording career of twelve studio albums, writing or co-writing almost all the band's material. He was the first Black Irishman to achieve commercial success in the field of rock music. Thin Lizzy featured several guitarists throughout their history, with Downey and Lynott as the rhythm section on the drums and bass guitar. As well as being multiracial, the band drew their early members not only from both sides of the Irish border but from both the Catholic and Protestant communities during The Troubles.
