Returning with their tenth full-length album, Norwegian symphonic Gothic act Sirenia continues both the good work and the alliteration of their last couple of studio outings with their latest release Riddles, Ruins & Revelations (Napalm Records). Operatic vocals, a robust rhythm section, pounding riffs and flighty keyboards dominate proceedings, punctuated by some expert lead guitar work and differing vocal styles. Adorned with thunderous breakdowns or quieter, slower sections each cut remains interesting rather than outstaying its welcome.
