The Half-Light Symphony is the first EP by New Zealand progressive rock band Battle Circus . A concept record depicting mankind's transitional stages of existence following a cataclysmic nuclear disaster, the EP is divided into four distinct movements that provide a narrative for each part of the story. The research and hypotheses of US-based academic Dr. Philip K. Mossman heavily influenced the band, and were central to the themes of the album. A recording of Dr. Mossman reciting a passage from his paper entitled "Epoch" was sent to the band by the now-deceased professor's wife, and was included in the final track "Mossman's Epoch". Throughout the New Zealand tour for the album the band would perform The Half-Light Symphony in its entirety, from start to finish.
The band commissioned renowned Japanese artist Ryohei Hase (www.ryoheihase.com) to create the artwork.
