Wishbone Ash are a British rock band who achieved success in the early and mid-1970s. Their popular albums included Wishbone Ash (1970), Pilgrimage (1971), Argus (1972), There's the Rub (1974), and New England (1976). 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).

In 1987, I.R.S. Records founder and original Wishbone manager Miles Copeland III began a series of albums entitled No Speak, which featured all instrumental music. To launch the label successfully, Copeland needed a big name band that would bring publicity to the project. Copeland approached the four founding members of Wishbone Ash about having the original line-up record an all-instrumental album. For the first time in fourteen years, Andy Powell and Steve Upton joined forces with Martin Turner and Ted Turner to record the album Nouveau Calls, released in February 1988. The original line-up's tour of 1988 was a huge success, as the band played large venues for the first time since the late 1970s. In August 1989, the band released a reunion album with vocals entitled Here to Hear, featuring mainly songs written by Ted and Martin Turner.  In 1990 the band went back into the studio to record the follow-up to Here to Hear. The band were shocked when founding member Upton, the band's drummer for their entire career, announced his retirement from the music industry. They enlisted drummer Robbie France, but replaced him with Ray Weston when it was determined that personal conflicts between France and Martin Turner could not be resolved. Strange Affair was released in May 1991.  Later in 1991, the band decided to continue without founding member Martin Turner, with the bassist/vocalist being replaced by returnee Andy Pyle, who had been in the band years earlier. The band toured throughout 1992/93, releasing the live album The Ash Live in Chicago. 1994 saw the second and final departure of Ted Turner. Following Turner's departure, Pyle and Weston also left the band.Answer this question using a quote from the following article:
