The years of constant heavy metal touring can be hard on a man. MOTÖRHEAD will not perform at tonight’s (Tuesday, February 28) Gigantour show at the Fillmore Auditorium in Denver, Colorado. The band’s founder, bassist and principal songwriter Ian “Lemmy” Kilmister has lost his voice and has decided to give it the night off. Things should be good to goK for the last three shows of the tour. The other bands on the Gigantour bill — MEGADETH, LACUNA COIL and VOLBEAT — will go ahead and perform this evening as scheduled.
