What to Do Tonight: Wishbone Ash

Four decades ago, Wishbone Ash were one of the vital secondary lights of the British prog-rock scene. Although bands like King Crimson, Yes and Traffic were attracting more of the media spotlight, Wishbone Ash were netting tons of FM radio airplay with a string of largely excellent albums in the ’70s (like their eponymous 1970 debut, 1974’s There’s the Rub and 1978’s No Smoke Without Fire). Wishbone Ash were also one of the first bands to champion the twin lead-guitar format, an innovation that earned original guitarists Andy Powell and Ted Turner accolades from Rolling Stone, which named them two of the Top 20 guitarists of all time. The band’s lineup has been in flux throughout its tumultuous history — seven guitarists! Eight bassists! Four drummers! — but founding member Powell has charted a steady prog-rock course for Wishbone Ash, regardless of who he’s playing with. Wishbone Ash play the Winchester (12112 Madison Ave., 216.226.5681) at 9 p.m. Tickets: $20. — Brian Baker
