Query: An anthem to how far metal has come in 35 years

Mixing acoustic folk, progressive rock, and death metal might seem difficult to pull off with class and panache, but this is just everyday work for a band like Opeth. Amazing riffs, wonderful vocals (both the brutal death growls and melodic singing passages), and skillful composition make this album simply one of the best albums ever. If you value great music, get this!!!
