The metal universe is chock full of legendary, long lasting acts who delivered album after album of excellence or at least some level of  consistency, even with a misstep or two; for example, Cannibal Corpse, Morbid Angel, Bolt Thrower, Dismember, Iron Maiden, Slayer, Incantation, Deicide, Suffocation etc.

But for every one of those bands that had the right recipe for longevity and quality, there are 50 or more that never ‘made’ it. And my made it, we mean they just had one killer album or EP and for any number of reasons, never followed that release up.
