Within Temptation have announced details of their 6th studio album Hydra which will be released on 3rd February 2014.

"It's like us - undefinable" laughs Within Temptation guitarist and songwriter Robert Westerholt. What's more, Hydra is a perfect title for our new album, because like the monster itself, the record represents the many different sides of our music.

Special guests on Hydra include Finnish operatic metal diva Tarja Turunen, acclaimed singer-songwriter Dave Pirner of Soul Asylum and metalcore hero Howard Jones, formerly of Killswitch Engage as well as US hip-hop icon Xzibit,.

Asked to describe Xzibit's performance on the song And We Run, Westerholt laughs: "Xzibit is amazing. This song is about how you've got to live your life now. He's rapping at full force on this song, it's really heavy." Sharon adds: "Xzibit brings a new element to our music that we've never had before! It's a new cross-over and we love it!" As for the mighty Tarja, den Adel recalls: "The way she delivers those high melody lines left us all speechless. We had a great time, and the fans responded beyond our expectations."

Hydra will also be available as a Special Edition double CD with the Media book, featuring 10 tracks on disc one and eight bonus tracks on disc two. There will be a double vinyl LP and a jewel-case CD version to complete the product range.
