Martin Barre began his musical career in the band Moonraker. Following the departure of Mick Abrahams at Jethro Tull their band leader Ian Anderson was on the search for a successor different guitarists audition, including Barre. But he decided first for Tony Iommi (later of Black Sabbath ). After this, however, had left the band after a short time, only Cash was invited to a second audition. This appeared with the guitar, but without amplifier; Anderson held his ear as close as possible to the instrument and was convinced despite the adverse circumstances. The first time with Jethro Tull he can be heard on the second album Stand Up.
In addition to the Guitar Barre dominated other instruments, including the flute. At a trademark were the sharp riffs and extended intermediate solos ever since the album Aqualung. Very pronounced is the be heard in title track of the album, Tull Minstrel in the Gallery.
Martin Barre was next to Anderson, the mainstay of the band. Occasionally, however, he also found time to work on their own projects. The results are now four solo albums. As Anderson and almost any other of the numerous current and former Jethro Tull members, Barre never gave cause for frequent in rock and pop business scandal headlines in the tabloids.
After his retirement in 2012 published at Jethro Tull Barre in September 2013 the solo album Away With Words. In the fall of 2013 he was, together with Jonathan Noyce (bass ), Frank Mead ( sax, flute, harmonica ), Pat O'May (guitar), Dan Crisp ( vocals, acoustic guitar) and George Lindsay (drums ) under the name Marin Barre & band on a European tour.
