OPETH.

Opeth, the Swedish prog metal band, is returning to their death metal roots after 16 years. Their new single, "Paragraph 1," features death metal vocals and sets the stage for their upcoming album, "The Last Will And Testament." The album is a concept record set in the 1920s, following the story of a father's death and the secrets revealed during the reading of his will. The band worked with Jethro Tull's Ian Anderson on the album, who provided narrations and even added a flute solo. Opeth's vocalist, Mikael Åkerfeldt, expressed his preference for intricate and technical death metal. [Extracted from the article]
