If Led Zeppelin is the stately grandfather in the extended family of hard
rock and Metallica is the bratty kid brother, Motorhead is the creepy great
uncle who lurks in the corner at holiday events, telling dirty jokes, drinking
too much grog and generally freaking out the neighbors, no matter how tattooed
and pierced the neighbors may be. However, there's a head-bangingly good reason
they get invited to partake: They're as important as anyone in the history of
heavy music. So when "Aftershock," their 21st studio album, drops this autumn,
it'll doubtless be well worth the listen.
