So I just had a goodl listen and I was a bit surprised. The single "Sarah (Bury Her)" is exactly that. It defintely has more of a commmerical vibe ala Delain. However, the majority of the disc is very early Nightwish oriented with speedy symphonic riffs highlighted with operatic chorus work that reminds you of Tarja and the band in their early prime. There is nothing on their Myspace page to give you a true direction of the disc.
Good stuff regardless.
