"Watershed" combines elements of modern metal, prog rock, free jazz and hints of European folk music, all of which come together for a seamless, unique collection of songs that will leave an indelible mark upon all who listen. The follow-up to 2005's "Ghost Reveries" is the first OPETH release to feature new guitarist Fredrik Åkesson and drummer Martin Axenrot and is the band's second effort for Roadrunner Records.
