"Retrovirus" collects a series of tracks from 1987 to 2000, and shows Bad Sector's typical ability to build menacing dark ambient tracks using a variety of different sources (here, for example, a phasing sequencer, a bowed copper wire, vocal samples etc.) with a great sense of structure and composition, but also at the same time a distinct "emotional" and visionary quality which is often missing in releases of this genre. The atmosphere is almost always gloomy and tense, which fits with the apparent virus theme, a relevant exception being "TCGT ", a perfect piece of soothing cosmic music.
