Down to just one original member, Blackie Lawless, the metal band with the mysterious acronym W.A.S.P., is alive and touring. In the 1980s, the group caught the attention of another acronym-loving organization, the PMRC (Parents Music Resource Center), led by Tipper Gore (the wife of Al), because of its strongly suggestive material, such as their debut single, titled "Animal (Fuck Like a Beast)." Now, with Tipper content to watch the music industry self-destruct, the band rocks on with what may be its last tour for some time. On this tour, W.A.S.P. will be performing its 1992 album "The Crimson Idol" in its entirety for the first time. While the meaning behind the letters in the name may never be revealed, fans of W.A.S.P. don't need to be told what the group stands for. W.A.S.P. plays Toad's Place Tuesday, Feb. 12, with Fatal Smile and Liquid Violence. $17.50-$20. 648-TOAD.
