Martin Lancelot Barre (born 17 November 1946) is an English rock musician best known for his work with progressive rock band Jethro Tull, with whom he recorded and toured from their second album in 1969 to the band's dissolution in 2014. In early 1990's he initiated a solo career that now spawned four studio albums plus several guest appearances.
He has also played the flute and other instruments such as the mandolin, both on-stage for Jethro Tull and in his own solo work.
Barre once said that he tried not to listen to other guitarists so that he would not be influenced by them. He said he never took guitar lessons so that he would not sound like other players. However, one guitarist he has praised and recognized as being an influence is Leslie West, from the American band Mountain.
Reviewers have sometimes described Martin Barre's sound as "tricky" and "complicated", highlighting his ability to compose melodies instead of simply soloing.
