Metalheads shouldn’t be discouraged that I’m ending my instrumental series with some progressive rock. On Larks’ Tongues In Aspic, Part One, King Crimson unleash the kind of demonic power that your average black metaller would gladly sacrifice their corpse-painted left bollock to have access to. Being a prog track, there are also plenty of other tangents and moods here, from muscular jazz funk to bucolic classical and a climax of ghostly voices and spellbinding lead bass from the late John Wetton. But the way the sung erupts from its twinkly opening and ominous violin into that diabolical, violent riff… there are no words.
