(Prog) Tarja Turunen has unveiled a track-by-track breakdown series for her latest album The Brightest Void. The former Nightwish singer has released the promo for the 'prequel' album to her upcoming release The Shadow Self, which is due out on August 5. It can be pre-ordered via her official website.

In one clip she talks about working with her friend Michael Monroe, former vocalist of Hanoi Rocks, on track Your Heaven And Your Hell. Tarja says: "He was very up for it - if he loves something he just goes for it. It was incredible, because we talked about the idea of the lyrics and the theme of the song together, and he appeared the next morning with the full lyrics done like, 'Hey, I wrote the lyrics.'

"It was fantastic. He is a super-fast and intelligent person, and I really liked how heavy it turned out to be. Hopefully, I can perform the song with him one day. We can figure it out." Watch the video here.
