Pioneering Metal Bands that Are No More

[Painkiller]

Motörhead, obviously. You can't call yourselves Motörhead without the late Lemmy Kilmister, regardless of who's who. His death put a massive dent. It'll never be the same again.

Black Sabbath is said to no longer be working together, but I'd say that Tony Iommi may still put out at least one more album before he passes.

Riot should've been considered dead since 2012. Absolutely no reason to continue as such without any original member.

I don't know how much longer Iron Maiden or Judas Priest have on this planet. Saxon is going out in a blaze of glory, though.
