In many ways, Opeth’s Blackwater Park can be considered as their answer to The Beatles’ Revolver, both uncompromising and experimental, but equally commercially viable and unfuckwithable masterpieces. Twenty years on, Blackwater Park remains a breath-taking piece of work, dense with extraordinary melodic moments, spine-tingling atmospherics and agile but crushing heaviness.

It is also arguably still the most cherished album in the Swedish metallers illustrious catalogue as a rising progressive influence kicked open prog’s ornate doors, fed death metal through the cosmic kaleidoscope and introduced a generation of music nerds to a world of limitless musical possibilities.
