Within Temptation have announced that they will release their sixth studio album, ‘Hydra,’ on Jan. 31. In addition, the Dutch band has revealed some unexpected surprises in the form of guest appearances on the disc.

Known for creating their own brand of symphonic metal, Within Temptation have a few surprises in store on ‘Hydra.’ The guest list includes collaborations with Dave Pirner of Soul Asylum, former Killswitch Engage frontman Howard Jones and perhaps the most surprising of them all – hip-hop artist Xzibit. The set also includes the recently released track 'Paradise (What About Us?)' featuring former Nightwish singer Tarja Turunen.

Xzibit joins forces with Within Temptation on a track called ‘And We Run,’ a song described by frontwoman Sharon Den Adel as an anthem about how to live your life. “He's rapping at full force on this song, it's really heavy,” says Adel. "Xzibit brings a new element to our music that we've never had before! It's a new cross-over and we love it!"

Jones' contribution comes on ‘Dangerous,’ one of the heavier tracks on the disc. “I always loved Howard's voice," shares Adel. "He makes the song even heavier than it already is. That song is one of my favorite songs on the record and one of the fastest we've ever written. It has the most bass drums we've ever used, too, and a very fast riff which we doubled with synths. It's not a typical synthesizer, though — it's distorted like a guitar, and it's very aggressive."

‘Hydra’ is currently available for pre-order in two different luxury formats – a digital premium version and a deluxe box set. The digital premium version also contains a handful of cover tunes including Within Temptation’s versions of Imagine Dragons' 'Radioactive' and Lana del Ray's ‘Summertime Sadness.’ Get full details on the album, as well as the pre-order info, at Within Temptation's official website.
