"The first Sabbath record just had the biggest impact on me. Because, when you think about it, in the landscape of all the other music that was happening at the time, there's this one dark record that comes out that really created what you would consider dark heavy metal and created the path for everything that was to follow. And so yeah, that record is especially poignant."
Slash then talks about his love of Black Sabbath's 1973 album Sabbath, Bloody Sabbath, adding that the title track has probably the heaviest riff of all time.
"And the title track, that breakdown towards the end of the song. There's just nothing that's ever come out that's heavier than that. Not one band that I can think of has a riff that is as heavy as 'Sabbath Bloody Sabbath.'"
Maybe not the heaviest riff of all time, but man – "Sabbath, Bloody Sabbath" does have some incredibly chunky riffs.
