Renaissance are an English progressive rock band, best known for their 1978 UK top 10 hit "Northern Lights" and progressive rock classics like "Carpet of the Sun", "Mother Russia", and "Ashes Are Burning". They developed a unique sound, combining a female lead vocal with a fusion of classical, folk, rock, and jazz influences. Characteristic elements of the Renaissance sound are Annie Haslam's wide vocal range, prominent piano accompaniment, orchestral arrangements, vocal harmonies, acoustic guitar, bass guitar, synthesiser, and versatile drum work. The band created a significant following in the northeast United States in the 70s, and that region remains their strongest fan base.

The band left Sovereign Records and joined Miles Copeland's new prog rock stable and label BTM (for British Talent Management). The label's first release was Turn of the Cards in 1974. With a larger budget, the album went from folk-flavoured to a more dark, lush, orchestral rock sound. One of the album's songs, "Things I Don't Understand", which clocked in at 9:30, was Jim McCarty's last co-writing credit with the group (although it was actually in the band's live repertoire for years). A lengthy tribute to Aleksandr Solzhenitsyn, called "Mother Russia", closed out the album, with lyrics inspired by his autobiographical novel, One Day in the Life of Ivan Denisovich. Turn of the Cards was first issued in the United States on Sire Records in August 1974, where it reached No. 94, some months before an official UK release. It remained in the Billboard 200 for 21 weeks. Although Renaissance's fan base was relatively small, its following was heavily concentrated in the large cities of the northeast US. The album was eventually released in the UK in March 1975. It was soon followed by Scheherazade and Other Stories, released on both sides of the Atlantic in September 1975. The album, whose second side was taken up with the epic tone-poem "Song of Scheherazade" based on stories from One Thousand and One Nights, peaked at No. 48 in the United States. There is "no musical connection to the well-known classical work Scheherazade by Nikolai Rimsky-Korsakov." A double live album, Live at Carnegie Hall, followed in 1976. Despite criticisms that much of the album was little more than a note for note reproduction of highlights from their previous four studio albums, the album reached No. 55 in the US. Renaissance were the first British band to sell out three consecutive nights at Carnegie Hall. They were joined on stage by the New York Philharmonic Orchestra. While introducing the song "Ashes Are Burning", Haslam refers to it as the title track from the group's second album, rather than their fourth, suggesting that the Haslam-led lineup by this point considered themselves a distinct band from Keith Relf's incarnation of the group. (This point is further underscored by the band's including an album discography in the gatefold of LP copies of Live at Carnegie Hall, which lists only the four albums from Prologue forward.) Live at Carnegie Hall's follow-up, Novella, saw more chart success in the US, peaking at No. 46 in 1977, although its UK release was delayed by yet another label change.
