Rock music is a broad genre of popular music that originated as "rock and roll" in the United States in the early 1950s, and developed into a range of different styles in the 1960s and later, particularly in the United Kingdom and in the United States. It has its roots in 1940s and 1950s rock and roll, a style which drew heavily on the African-American genres of blues and rhythm and blues, and from country music. Rock music also drew strongly on a number of other genres such as electric blues and folk, and incorporated influences from jazz, classical and other musical styles. Musically, rock has centered on the electric guitar, usually as part of a rock group with electric bass, drums, and one or more singers. Typically, rock is song-based music usually with a 4/4 time signature using a verse-chorus form, but the genre has become extremely diverse. Like pop music, lyrics often stress romantic love but also address a wide variety of other themes that are frequently social or political.
By the late 1960s "classic rock" period, a number of distinct rock music subgenres had emerged, including hybrids like blues rock, folk rock, country rock, raga rock, and jazz-rock, many of which contributed to the development of psychedelic rock, which was influenced by the countercultural psychedelic and hippie scene. New genres that emerged included progressive rock, which extended the artistic elements; glam rock, which highlighted showmanship and visual style; and the diverse and enduring subgenre of heavy metal, which emphasized volume, power, and speed. In the second half of the 1970s, punk rock reacted by producing stripped-down, energetic social and political critiques. Punk was an influence in the 1980s on new wave, post-punk and eventually alternative rock. From the 1990s alternative rock began to dominate rock music and break into the mainstream in the form of grunge, Britpop, and indie rock. Further fusion subgenres have since emerged, including pop punk, electronic rock, rap rock, and rap metal, as well as conscious attempts to revisit rock's history, including the garage rock/post-punk and techno-pop revivals at the beginning of the 2000s.
Pink Floyd are an English rock band that initially earned recognition for their psychedelic or space rock music, and, as they evolved, for their progressive rock music. They are known for philosophical lyrics, sonic experimentation, innovative cover art, and elaborate live shows. One of rock music's most successful acts, the group have sold over 200 million albums worldwide including 74.5 million albums in the United States alone.
Pink Floyd had moderate mainstream success and were one of the most popular bands in the London underground music scene in the late 1960s as a psychedelic band led by Syd Barrett; however, Barrett's erratic behaviour eventually forced his colleagues to replace him with guitarist and singer David Gilmour. After Barrett's departure, singer and bass player Roger Waters gradually became the dominant and driving force in the group in the late-1970s, until his eventual departure from the group in 1985. The band recorded several albums, achieving worldwide success with The Dark Side of the Moon (1973), Wish You Were Here (1975), Animals (1977), and The Wall (1979). In 1985, Waters declared Pink Floyd "a spent force", but the remaining members, led by Gilmour, continued recording and touring under the name Pink Floyd. Although they were unsuccessfully sued by Waters for rights to the name, they again enjoyed worldwide success with A Momentary Lapse of Reason (1987) and The Division Bell (1994). Eventually they reached a settlement out of court with Waters allowing them use of the name. Waters performed with the band for the first time in 24 years on 2 July 2005 at the London Live 8 concert.
