The music of the Swedish group Graveyard gives you a jolt, but in a good way.
The band's drummer is Axel SjÃ¶berg and he's the one responsible for giving the band its jolt.
Rock drumming is a tough gig, physically.
"I guess it exhausts me because it's quite energy draining to play live," SjÃ¶berg says.
But he also admits, it's fun.
