These Three Japanese Grandpa’s Can Metal!
While you might be expecting some sort of golden-aged parody from the Land of Weird - Japan... These dudes can rock! And while calling them grandpa's isn't exactly accurate, they embrace it. In fact, if you check out their wiki page, the average age in the band is just three years older than Dave Grohl, but still younger than OG Metallica. Still, I digress... Their sound is on point, and available just about everywhere online.
