Dutch symphonic rockers WITHIN TEMPTATION took part in a press conference on June 18 at Hellfest in Clisson, France. You can now watch the question-and-answer session below.

Asked when fans can expect to see the follow-up to WITHIN TEMPTATION's sixth studio album, "Hydra", which came out in January 2014, frontwoman Sharon Den Adel said: "At the moment, we have started [the songwriting process], but we're not that far yet; there's no release date yet."

Regarding a possible concept or special lyrical theme that will be covered on the upcoming WITHIN TEMPTATION album, Sharon said: "We always try to find some kind of angle that makes this album different towards the other ones. Like last time, we had a lot of guest appearances and the comics before that one [2011's 'The Unforgiving']. We'll come with something new again. We have several options, but we're not definite on that yet. It's all part of the big surprise, of course, also."

Former NIGHTWISH singer Tarja Turunen joined WITHIN TEMPTATION on stage at Hellfest to perform the song "Paradise (What About Us?)". Professionally filmed video footage of her appearance — preceded by the WITHIN TEMPTATION song "Mother Earth" — can be seen below.

The studio version of "Paradise (What About Us?)" — also featuring Tarja — can be found on "Hydra".

Sharon previously stated about the band's collaboration with Turunen: "When we had written the first version of 'Paradise' and listened back to the demo we'd recorded and the epic power of the song, we thought of Tarja instantly. How well this track would fit her classical voice and how extra special it would be if we sang it together. The more we thought about this wild idea, the more excited we got about it!"
