Satan's Fall could have been split into three separate songs and each one of those songs would be a better song than the other two songs remaining here. The single greatest collection of riffs of all time.
... the guy who has Blood In, Blood Out in his 2014 list is talking to me about good riffs, lmfao. And you clearly let your bias seep through when talking about music so nothing you say means much to me.
I don't even like Mercyful Fate all that much and I think Satan's Fall is a fucking fantastic collection of riffs. Not sure about best ever (Adramelch - Zephirus or something) but certainly up there. Not that me agreeing with HBB is going to make you take his opinion more seriously.
