Chiropractors, rejoice. Expect a surge in appointments after Motörhead puts their fans into a head-banging frenzy next week. The veteran rock band has been pounding out their punk-metal music for almost 30 years, influencing more mainstream acts such as Metallica and Guns N’ Roses. While never gaining the kind of crossover success of these bands, Motörhead has a loyal following around the world. Their best-known albums include: Overkill, Ace of Spades, and their live album, No Sleep ’Til Hammersmith. Motörhead has endured several line-up and record label changes over the years, but founding member, singer and bassist, Lemmy Kilmister, remains a constant presence in the band. When he isn’t playing with Motörhead, Lemmy contributes his bass-playing and songwriting talents to other rock artists such as Ozzy Osbourne, Lita Ford and Nina Hagen. Motörhead, whose latest release is Hammered, plays April 22 at New Oasis. The Dwarves and High on Fire open the 8:30 p.m. all-ages show. Tickets are $20 in advance and $22 at the door. New Oasis is at 2100 Victorian Ave., Sparks. Call 359-4020 or visit www.newoasisreno.com.
