HERESIEUnivers Zero's debut recording, 1313, may be somber, but it's a walk in the park compared to their second release, which features more or less the same lineup as the first (oboe, bassoon, viola, violin, bass, guitar, keyboards, drums), except for an additional and prominent contribution of cathedral organ from guitarist keyboardist Roger Trigaux. Studio overdubbing sometimes gives the five man group the sound of a much larger chamber ensemble.
