Conclusion of an Age is the debut album from Sylosis, a British metal band from Reading, Berkshire. The album was released on 24 October 2008 and was produced and recorded by Scott Atkins at Grindstone Studios. It was also the last release by the band to feature Jamie Graham on vocals.
Although it is not strictly a concept album, there is a theme running throughout the album that relates to the collapse of human civilization and the return of the Earth to its natural state. The band stated in a press release that the album's lyrical theme deals with "the direction in which the planet is heading and the consequences humanity will face. The album covers many areas, but the main concept is the idea of mankind destroying itself through war, self-indulgence, religion etc. and how the earth is being ravaged by humanity to the point of being destroyed... but how the Earth's might will eventually prevail!"
