Back in the day heavy metal meant Black Sabbath and NWOBHM; lots of grunt, powerful vocals, but no cookie monster growling !
Nowadays with the predominance of death metal, melodic death metal, dom, suicide metal, black metal, Ihaveamentalhealthproblem metal we hear alot of people sounding like they need to take themselves slightly less seriously
Take these guys, for example, Meshuggah; they need a cuddle !
On the otherhand what about Opeth or Gojira ? Intelligent growlers, greeny growlers with not a psychiatrist in sight
Whats your view ? To growl or not to growl ? Let me know about metal bands that do it well, with no exorsism needed after you listen.....
