1970 was a year of change in pop and rock music, with divisions between both becoming ever more blurred. More ambitiously-constructed epics, heavy rock numbers and contemporary folk songs competed with mainstream and easy listening fare on Top of the Pops and in the Top 30 singles, while progressive and jazz-rock took their bow in the album charts. Some acts disbanded, notably The Beatles, all of whom relished their freedom and launched solo careers, and Simon & Garfunkel, or else parted company and partially regrouped under new names.

Festivals came into their own, particularly in Britain where the first Glastonbury event was launched, as did live albums, notably from The Rolling Stones and The Who, partly to combat the market in bootleg recordings; several singer-songwriters found major acceptance; the death of Jimi Hendrix was widely mourned; and the likes of Marc Bolan, Elton John, Rod Stewart (as a soloist, and as front man of The Faces), Lindisfarne and Hot Chocolate achieved their initial successes. By the end of the year, many a critic and music fan could look back on a 12-month period in which their landscape had altered almost beyond recognition.

This is the story of that year and the key albums that helped define it.
