Fairport Convention are a British folk rock band. Formed in 1967, they are widely regarded as a key group in the English folk rock movement. Their seminal album Liege & Lief is considered to have launched the British folk rock movement, which provided a distinctively English identity to rock music and helped awaken much wider interest in traditional music in general. The band have drawn heavily on the Child Ballads, songs of the British Isles from the later medieval period until the 19th century.

In 1998, Dave Mattacks moved to the USA and Gerry Conway took over on drums and percussion. Fairport produced two more studio albums for Woodworm Records: The Wood and the Wire (2000) and XXXV (2002). Then for Over the Next Hill (2004) they established a new label: Matty Grooves Records. In this period the band toured extensively in the UK, Europe, Australasia, Europe, the USA and Canada, and staged a major fund raiser for Dave Swarbrick at the Birmingham Symphony Hall. In 1998, members of the band began their association with the Breton musician Alan Simon. Working in collaboration with numerous others, members of Fairport (predominantly Nicol and Leslie) have performed in and participated in the recordings of all Simon's rock operas, including the Excalibur trilogy (1998, 2007, 2010) and Anne de Bretagne (2008).  2007 was their fortieth anniversary year and they celebrated by releasing a new album, Sense of Occasion. They performed the whole of the Liege & Lief album live at Cropredy, since 2004 renamed Fairport's Cropredy Convention, featuring the 1969 line-up of Dave Swarbrick, Ashley Hutchings, Dave Mattacks, Simon Nicol and Richard Thompson, with singer-songwriter Chris While taking the place of Sandy Denny. Footage of the festival, although not the Liege and Lief performance, was released as part of a celebratory DVD.  The band's first official YouTube video appeared in April 2008. Edited from footage shot for the DVD, the nine-minute mini-documentary includes interviews with Lulu, Jools Holland, Seth Lakeman, Mike Harding, Geoff Hughes and Frank Skinner.  In 2011, the band released a new studio album Festival Bell, the first new album in four years. This was followed in 2012 by Babbacombe Lee Live Again recorded live during the 2011 tour revisiting the Babbacombe Lee album first issued in 1971. In 2012, the band also released By Popular Request, a reworking in the studio of a number of the most popular songs in the band's repertoire (as determined by a mysterious consultation and voting process conducted by the band with its fans).  In January 2015, four years after their previous studio album of original material (Festival Bell), Fairport Convention released a new one entitled Myths and Heroes.
