The excellently-named Meshuggah is a "technical death metal" band from Sweden. While I appreciate their musical experimentation, the singer's angry growl is a bit much for me. I was delighted when my pal Patrick Kelly pointed me to this great video of Meshuggah's guitarist Fredrik Thordendal shredding with great joy along with Morgan Ågren, the drummer in Thordendahl's side project Special Defects. Those grins are infectious. As Pat says, this here is Happy Metal!
