Wishbone Ashes

There are two different touring versions of Wishbone Ashes, both of which feature exactly one original member from the British prog/hard-rock group. The Wishbone Ash that plays an 8 p.m. show at Shank Hall tonight is the better regarded of the two, led by original guitarist Andy Powell. When Powell seized control of the band in the mid-'90s, he took the group in some unorthodox directions--infamously recording a pair of dance-inspired records under the Wishbone Ash brand name--but he's since turned the group into a less-contentious, classic-rock nostalgia act, releasing a never-ending stream of live albums.
