How three lads from Newcastle inspired the biggest metal band in the world and inadvertently named a genre.

With their stage names Cronos (Conrad Lant), Mantas (Jeffrey Dunn) and Abaddon (Anthony Bray), the classic line-up of Venom were already setting a precedent for showmanship that would be picked up by later bands.

But it was the sound of their 1981 Welcome To Hell debut that would inspire so many with its groundbreaking speed and Bulldozer Bass sound. Indeed none more so than the young musicians who would form Metallica and support them on tour in 1984.

But while Venom's satanic themes, harsh vocals and stage attire were somewhat tongue in cheek, over in Scandinavia it was all taken with utter seriousness. So much so that a whole movement was spawned in namesake of Venom's second album from 1982.

Black Metal.
