Since their album 'Retaliation', Obscenity went through many changes. The most obvious being the additions of vocalist Manuel Siewert (December Flower) and bass axe man David Speckmann (Burial Vault). Both are now presenting their recording debuts with Obscenity on 'Summoning The Circle', accompanied by the band's veterans Hendrik Bruns (guitar) and Sascha Knust (drums) as well as guitarist Christoph Weerts.
