Katatonia and Opeth have historically been muttered in the same breath as fellow impresarios of fugue metal, even if the former hasn't been anything remotely close to metal in quite some time. Of course, the bands shared Mikael Åkerfeldt through the Nineties, so they were bound to share the spotlight as well. Over the years, however, the two bands have become divisible even while rolling as touring mates. Since "Discouraged Ones" and "Last Fair Deal Gone Down", Katatonia have taken ongoing steps away from a pure metal path. Opeth continues to embrace it while exploring new courses, as "Damnation" and most recently, "Heritage", have proven. In both cases, their progressive refinement is world-class.
