Watershed is the ninth full-length studio album by the Swedish heavy metal band Opeth. Released by Roadrunner Records, Watershed is the first studio album by Opeth to feature guitarist Fredrik Åkesson and drummer Martin Axenrot, who replaced longtime guitarist Peter Lindgren and drummer Martin Lopez. The artwork for the album was made by Travis Smith (who has created the artwork for eight previous Opeth releases) in collaboration with Mikael Åkerfeldt. The album has been described as "a major turning point" for Opeth due to the depth of its engagement with progressive rock. It is also, as of 2014, the band's last studio album to contain death growls.
