I think people tend to mix up heaviness with brutality and extremity. Well at least my interpretation of heaviness anyway. I consider something like Candlemass’ The Well of Souls to be heavier than a lot of death metal for example - the riffs are just so weighty and forceful.
There are levels of heaviness. Iron Maiden are not heavier than say Black Sabbath, that doesnt mean they arent heavy when compared to the rest of the music that was being played at the time. I bet you argued with them that Iron Maiden aren't even a heavy metal band, right?The lead guitarist in my first band way back was very old school in his taste and he considered Iron Maiden to be "heavy". Being knees deep into Sepultura, MachineHead, Pantera... at the time myself, all the groove bands with chunky power chords and muffled palm muted sections, I couldn't even wrap my mind around the concept someone could even consider Iron Maiden "heavy". Otherwise I've come across many acceptations of the term "heavy" I didn't agree with, so thought it'd be interesting to read opinions..
i think the Sabbathy crushing main riff on Children of the Dead is the heaviest they've been. But i havent heard a bunch of their newer albums so i could be wrong.Maiden aren't very heavy. They're metal as fuck though. Powerslave is probably their heaviest song.
Actually come to think of it one of their newer albums showcases a little bit a visceral low-end type of stuff. If you haven't heard this you might be shocked that Maiden can produce this kind of stuff. The first 4 mins in particular.i think the Sabbathy crushing main riff on Children of the Dead is the heaviest they've been. But i havent heard a bunch of their newer albums so i could be wrong.
All various forms of "heavy" that don't sound anything alike:
I think referring to music as "heavy" probably came from the 60's hippie culture, which meant that something was serious or intense and in the cultural lingo of the time it was something that wasn't a fun time or a kind of buzzkill.
Heavy metal was also in the air, in the water, and in the news throughout 1969. Heavy metal was the popular term for one heavy metal, mercury, which was polluting the air and poisoning fish and those who ate them.
