In this day and age female fronted metal bands are normal part of everyday life. They are so common, in fact, that it's a waste of breath making the distinction between them and bands with a hairy, ugly guy behind the microphone. There was a time, however, when the idea of a woman fronting a full-on metal band was dismissed by metal fans and press alike as absurd. The world accepted Doro Pesch fronting Warlock and Sabina Classen leading Holy Moses in the '80s, sure, but it wasn't until the rise of The 3rd And The Mortal, The Gathering and Theatre Of Tragedy in the early '90s that the movement towards equality in metal truly began. Now, in celebration of a revolution that launched an entirely new musical genre, vocalists Kari Rueslåtten (The 3rd And The Mortal), Anneke van Giersbergen (The Gathering) and Liv Kristine Espenaes Krull (Leaves' Eyes, Theatre Of Tragedy) have united for a journey into the past presented live on stage: The Sirens.

The seeds for The Sirens were planted when Anneke approached Kari in early 2013 with the proposal of doing a duet for her Drive album (released in 2013). Regarded by Anneke as an inspiration going in to do The Gathering's breakthrough album, Mandylion, her intention was to pay tribute to Kari via the collaboration. The song didn't make the final cut as it didn't fit the album, but they remained in touch. Then, in July 2013 Anneke and Liv had a chance meeting at the Masters Of Rock festival in the Czech Republic, and The Sirens concept was born.

"We had a few minutes only to talk in between our gigs," Liv recalls, "but we agreed that we really should get together and tour. We both had to smile then, thinking that we were, with Kari, the 'originals' within our scene. Moreover, all three of us being mothers and still highly busy in music and art. Anneke told me that she had just talked to Kari, and that was the 'go' for The Sirens"

It would be fair to call Kari the catalyst for The Sirens, as both Anneke and Liv saw her as a role model when they first made their way into music.

"I find it hard to believe that I once inspired them," Kari admits, "but if so it is truly flattering. It is a fantastic feeling to know that I will be singing live with two such amazing vocalists!"

The Sirens tour will be split into two parts, including festival appearances, and staged at the end of 2014 in October and December. It will be a full concert showcasing the trio, one band, and a setlist featuring songs from The 3rd And The Mortal, The Gathering and Theatre Of Tragedy as well as tracks from Kari, Anneke and Liv's respective solo careers. They will sing alone, perform duets, capping off the night with all three of them on stage, with a show that is expected to clock in at around 100 minutes each night. Thus, it's a trip down memory lane produced for the here and now with brand new and unexpected elements, making The Sirens a nostalgia-fuelled reminder of who started it all and why it worked. And at the end of the night nobody will leave disappointed.

"The female fronted scene has become so big all over the world, sometimes it's hard to believe the three of us were at the very beginning of it," says Anneke. "I am very proud of that. Without intentionally wanting to start a new genre, our bands made it okay to sound and look as a girl singer on a metal stage. It was all very new and exciting. I think the tour is great to, in a way, celebrate those early days now that a third-wave of bands is appearing on the scene."

There are noteworthy parallels in the lives of Kari, Anneke and Liv that bind them together. All three fronted influential bands, they went on to have lucrative solo careers and remain active, and they've successfully balanced music with family life. It's clear the trio share a chemistry that will make The Sirens a rousing success.

"I'm looking forward to it a lot," Anneke says. "Making music with kindred spirits is such a wonderful feeling. I also love harmonizing with more than one singer on stage, so that will be a cool aspect of the show as well."

"The fans have been waiting for this for years and years," Liv adds. "I can't wait to share stage with Kari and Anneke. They are absolutely lovely and we have so much in common. This is a kind of magic."
