ALL THAT REMAINS singer Phil Labonte has contributed guest vocals to "What Lies Beneath", the new solo album from former NIGHTWISH frontwoman Tarja Turunen. Labonte appears in the track "Dark Star", which Turunen describes as a "duet." Tarja states, "I haven't been really working with such impressive vocals before. With [Phil's vocal contributions], the song reached another dimension."

With production handled by Tarja herself and selected tracks currently being mixed by U.K. producer Colin Richardson (pictured below with Tarja; famed for his work with MACHINE HEAD, BULLET FOR MY VALENTINE and SLIPKNOT, among others), the follow-up to 2007's "My Winter Storm" "looks set to take Tarja's unique musical mix of drama 'n' decibels to a whole new level of success," according to a press release.

"Colin has been working very hard on the songs and he does his job carefully, with lot of thought and passion," Tarja says.

"It has been nice to see that he seems to like what he hears, so it probably makes him work even better

"I am very happy with what I can hear so far. These songs that are going through his fingers are definitely sounding lot heavier than any of the songs from my last record.

"Just the sonic difference in guitars makes the songs radically heavier.

"I have always liked how he treats the guitars with the bands that he works with, like SLIPKNOT, for example.

"Anyway, you cannot expect me to make only a heavy metal album either. I am making Colin sweat with cellos, orchestras, choirs and sound ambient design."

Turunen will unveil the cover artwork for "What Lies Beneath", next week via her official web site.

"We worked on 33 songs this time around from which I decided to record 17," Tarja explained. "It has been great to have the freedom to produce my own record for the first time; these sessions have been such a gift, a real learning process and a true joy. In many ways, it feels like the first time…"

The lead single from "What Lies Beneath", title to be confirmed, is currently being discussed for an early August release, with the full album to follow later that month.

Turunen performed the song "The Good Die Young" with German hard rock veterans SCORPIONS on the March 27 edition of Germany's talk show "Wetten, Dass..?" The program also featured an interview with Tarja and SCORPIONS members Rudolf Schenker and Klaus Meine.

"The Good Die Young" appears on SCORPIONS' final studio album, "Sting In The Tail", which was released in North America on March 23 via Universal Music Enterprises.
