Dave Swarbrick (born 5 April 1941) is an English folk musician and singer-songwriter. He has been described by Ashley Hutchings as 'the most influential [British] fiddle player bar none' and his style has been copied or developed by almost every British, and many World folk violin players that have followed him. He was one of the most highly regarded musicians produced by the second British folk revival, contributing to some of the most important groups and projects of the 1960s, he became a much sought-after session musician, which has led him throughout his career to work with many of the major figures in folk and folk rock music. His work for the group Fairport Convention from 1969 is usually credited with leading them to produce their seminal album Liege and Lief (1969) which initiated the electric folk movement. This, and his subsequent career, helped create greater interest in British traditional music and was highly influential within mainstream rock. After 1970 he emerged as Fairport Convention's leading figure and guided the band through a series of important albums until its disbandment in 1979. Since then he has played in a series of smaller, acoustic units and engaged in solo projects which have maintained a massive output of recordings, a significant profile and have made a major contribution to the interpretation of traditional British music. He is married to the painter Jill Swarbrick-Banks.
