70s

Elton John became the decade’s biggest solo pop star, releasing diverse styles of music that ranged from ballads to arena rock; some his most popular songs included “Crocodile Rock”, “Goodbye Yellow Brick Road”, “Bennie and the Jets”, “Philadelphia Freedom”, and “Don’t Go Breaking My Heart” (the latter a duet with Kiki Dee). Other European soft rock major artists of the decade included Cat Stevens, Fleetwood Mac, and Joan Armatrading.

One of the biggest bands of the 1970s were the UKs Bee Gees who dominated the 1970s music scene having a string of number one hits and albums in the U.K. the U.S. and Europe they have generally been considered one of the most important acts of the 1970s and one of the most influential and important acts of all time, selling over 220 million albums worldwide to date and have generally been regarded as the decades biggest band.

One of the most successful European groups of the decade, and one of the best-selling acts of all time with 380 million records sold, was the quartet ABBA. The most successful Swedish group of all time, ABBA first found fame when they won the 1974 Eurovision Song Contest. They became one of the most widely known European groups ever, as well as one of the few groups from a non-English speaking country to gain international success with several back-to-back No. 1 albums and singles in most of the major music markets. “Waterloo”, “Mamma Mia”, “Take a Chance on Me”, “Knowing Me, Knowing You”, “Dancing Queen”, and “The Winner Takes It All” are just some of ABBA’s most popular and most successful songs.

New wave

In the late 1970s, many bands in the United Kingdom began experimenting with synthesizers, forming the new wave style known as synthpop. Major synthpop bands around this time included Gary Numan and Tubeway Army, the Buggles, the Human League, and Orchestral Manoeuvres in the Dark. Other successful British new wave bands in the late 1970s included the Police, Echo & the Bunnymen, Adam and the Ants, Roxy Music, Squeeze, XTC, the Cure, the Stranglers, Joy Division, and Siouxsie and the Banshees.

Rock

One of the first events of the 1970s was the break-up of The Beatles in the spring of 1970. Paul McCartney formed a new group, Wings, and continued to enjoy great mainstream success. The three other former Beatles — John Lennon, George Harrison, and Ringo Starr — all continued hugely successful recording careers throughout the decade and beyond. Lennon, McCartney, and Harrison all released extremely successful solo albums in 1970, Imagine, McCartney, and All Things Must Pass, and several of their songs are listed among the biggest hits of the 1970s: Wings’ “Silly Love Songs” and “My Love,” and Harrison’s “My Sweet Lord”.”

Hard rock

Heavy metal music gained a cult following in the 1970s, led by Led Zeppelin, Black Sabbath, and Deep Purple, with their styles later influencing other bands like Judas Priest and Motörhead, which eventually started the New Wave of British Heavy Metal in the 1980s.

Black Sabbath, formed in 1968 (as The Polka Tulk Blues Band, then Earth), is often credited with inventing the metal genre as well as stoner rock, doom metal, as well as sparking a revolution with much darker lyrics than were the norm in rock at that time.

Progressive rock

Progressive or prog rock developed out of late 1960s blues-rock and psychedelic rock. Dominated by British bands, it was part of an attempt to elevate rock music to new levels of artistic credibility. Progressive rock bands attempted to push the technical and compositional boundaries of rock by going beyond the standard verse-chorus-based song structures. The arrangements often incorporated elements drawn from classical, jazz, and world music. Instrumentals were common, while songs with lyrics were sometimes conceptual, abstract, or based in fantasy. Progressive rock bands sometimes used “concept albums that made unified statements, usually telling an epic story or tackling a grand overarching theme.” King Crimson as well as the Moody Blues have been seen as the bands who established the concept of “progressive rock”. The term was applied to the music of bands such as Yes, Genesis, Pink Floyd, Jethro Tull, Rush, and Emerson, Lake & Palmer. It reached its peak of popularity in the mid-1970s, but had mixed critical acclaim and the punk movement can be seen as a reaction against its musicality and perceived pomposity. Nevertheless, Pink Floyd’s 1973 release, The Dark Side of the Moon, was an immediate success, remaining in the charts for 741 weeks from 1973 to 1988, with an estimated 50 million copies sold. It is Pink Floyd’s most commercially successful album and one of the best-selling albums worldwide. It has twice been remastered and re-released, and has been covered in its entirety by several other acts. It spawned two singles, “Money” and “Time”. In addition to its commercial success, The Dark Side of the Moon is one of Pink Floyd’s most popular albums among fans and critics, and is frequently ranked as one of the greatest rock albums of all time.

Glam rock

Glam or glitter rock developed in the UK in the post-hippie early 1970s. It was characterized by outrageous clothes, makeup, hairstyles, and platform-soled boots. The flamboyant lyrics, costumes, and visual styles of glam performers were a campy, playing with categories of sexuality in a theatrical blend of nostalgic references to science fiction and old movies, all over a guitar-driven hard rock sound. Pioneers of the genre included David Bowie, Roxy Music, Mott the Hoople, Marc Bolan, and T.Rex. These, and many other acts straddled the divide between pop and rock music, managing to maintain a level of respectability with rock audiences, while enjoying success in the singles chart, including Queen and Elton John. Other performers aimed much more directly for the popular music market, where they were the dominant groups of their era, including Slade, Sweet, and Mud. The glitter image was pushed to its limits by Gary Glitter and The Glitter Band. Largely confined to the British, glam rock peaked during the mid-1970s, before it disappeared in the face of punk rock and new wave trends.

Soft rock

From the late 1960s it became common to divide mainstream rock music into soft rock and hard rock. Soft rock was often derived from folk rock, using acoustic instruments and putting more emphasis on melody and harmonies. It reached its commercial peak in the mid- to late-1970s with acts like the reformed Fleetwood Mac, whose Rumours (1977) was the best-selling album of the decade. Major British soft rock artists of the 1970s included 10cc, Mungo Jerry, the Hollies, and Rod Stewart. Some of the most successful singers and songwriters were Cat Stevens, Steve Winwood, and Elton John.

Punk rock

The mid-1970s saw the rise of punk music from its protopunk-garage band roots in the 1960s and early 1970s. The Sex Pistols and The Clash were some of the earliest British acts to make it big in both the United Kingdom and the United States. Groups like the Clash were noted for the experimentation of style, especially that of having strong ska influences in their music. Punk music has also been heavily associated with a certain punk fashion and absurdist humour which exemplified a genuine suspicion of mainstream culture and values. The Sex Pistols caused a major sensation in 1977 and were the first serious challenge to the established rock groups like the Rolling Stones and Led Zeppelin, although the punk era in Britain lasted only three years and effectively ended with the Pistols’ breakup.
