The name of the band's sixth studio album, Hydra, refers to this great variation in the band's main sound, as Westerholt said: "'Hydra' is a perfect title for our new album because like the monster itself, the record represents the many different sides of our music.” American magazine Aquarian Weekly considered the title highly appropriate and compared it to the band's diverse musical history, alleging that they were able to find the right balance between all the musical changes and, during the following tour, the sextet was also referred to as "a band that defy stereotypes".
