Wishbone Ash is a British rock band that was formed in Torquay, Devon, in 1969. The band, known for its distinctive dual lead guitar style, was a significant contributor to the development of twin-lead guitar hard rock. Original members Martin Turner and Andy Powell were central to the band's signature sound, which blended elements of rock, folk, and progressive music. Among their most influential works is the album "Argus" (1972), widely regarded as a cornerstone of the twin-lead guitar genre.
