Martin Lancelot Barre (born 17 November 1946, Kings Heath, Birmingham, West Midlands, England) is an English rock musician. Barre has been the guitarist for rock band Jethro Tull since 1969. He has appeared on every Jethro Tull album except their debut This Was. His sound has been marked by a blend of Jeff Beck and Eric Clapton style blues with the baroque complexities of early 1970s progressive rock and traditional European folk music sounds. He has also acted as a flautist both on-stage for Tull, and in his solo work.
