Strangling From Within was released on 23 November 1999 by the Avant-garde metal project Peccatum. The themes on this album can mostly be described as symphonic and neo-classical as well as the more prominent black metal influences.
Female Vocalist Ihriel contributes largely to the operatics and symphonic feel of the album. This is further achieved through use of various classical instruments that feature briefly or that may have a more pronounced role. Namely violins, cellos and harpsichords which are often played during sections of ambience and spoken interludes.
