When post-punk pioneers Wire reformed in 1986 after little more than a half-decade hiatus, they toured with an opening band, The Ex-Lion Tamers, whose set consisted of a note-perfect track-by-track recreation of Wire's debut album Pink Flag. This was a clever sop to the old guard fans who had come hoping to hear the oldies that the band clearly was no longer interested in performing, and it freed the band to concentrate on their new material.
Clearly such integrity is, unlike these many newly zombified bands, a thing of the past.
