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 and vocal harmonies.

The band was founded by vocalist Keith Relf and drummer Jim McCarty, formerly of the Yardbirds; along with John Hawken, Louis Cennamo and Relf's sister Jane. They intended to put "something together with more of a classical influence". Renaissance released their self-titled debut album in 1969, but fell apart during the sessions for their follow-up, Illusion (1971). New musicians were brought in to complete the record, and Renaissance was kept active through a period of fluctuating personnel until none of the original lineup remained, although McCarty continued providing compositions for the band to record for several more years. By 1972, a stable lineup consisting of Annie Haslam, Michael Dunford, John Tout, Jon Camp, and Terry Sullivan solidified. Aside from McCarty, they were assisted with lyrics on many songs from Cornish poet Betty Thatcher-Newsinger. From 1972 to 1979 Renaissance released seven studio albums, toured extensively, and sold out three nights in a row at Carnegie Hall with Tony Cox conducting the New York Philharmonic. The band's success was largely concentrated in the United States, where they built a cult following.

Renaissance struggled through the 1980s with personnel changes and two relatively unsuccessful studio albums, leading to disbandment in 1987. Two different offshoots of the band existed at the same time at one period in the mid-1990s. The band re-formed in 1998 to record Tuscany, which was eventually released in 2001; however, they broke up again the next year. A new iteration of Renaissance, led by Haslam and Dunford, debuted in 2009, and since then the band has continued to record and tour. Dunford died in November 2012. Later, Haslam stated that the band would continue touring. In 2013, they released the studio album Grandine il Vento, re-released the following year under the title Symphony of Light.
