Wishbone Ash are a British rock band who achieved success in the early and mid-1970s. Wishbone Ash are noted for their extensive use of the harmony twin lead guitar format which had been attracting electric blues bands since Jeff Beck and Jimmy Page had played together in the Yardbirds in 1966.Their contributions helped Andy Powell and Ted Turner to be voted "Two of the Ten Most Important Guitarists in Rock History" (Traffic magazine 1989), and to appear in the "Top 20 Guitarists of All Time" (Rolling Stone). Melody Maker (1972) described Powell and Turner as "the most interesting two guitar team since the days when Beck and Page graced The Yardbirds". They have been cited as an influence by Iron Maiden founder and bassist Steve Harris, as well as Thin Lizzy and other dual guitar bands. CD1 is Liverpool 1976 concert. CD2 is the 1992 Chicago concert.
