One Hour by the Concrete Lake takes a more thorough and factual approach to its concept than its predecessor, Entropia. A number of facts are given in the album booklet, with a list of sources provided at the end. The chronological order of songs is the same as the track order (as opposed to Entropia) and a number of the events and places are real. For example, the Black Hills in North America and Lake Karachay in the former USSR. The sound is generally darker and more subdued than Entropia, with a harsh, industrial feel to the guitar tones.
