CMX's following album, "Talvikuningas" (2007), was a space-themed rock opera and contains only one song, divided onto 12 tracks without pauses. Originally, the story about the power and fall of the Winter King (Talvikuningas in Finnish) was going to be the story of a novel by Yrjänä. The first edition of the album was soon sold out despite being much more expensive than a regular album. The press reviews were largely positive. "Helsingin Sanomat" newspaper called the album CMX's "third bullseye" after "Aura" and "Aion", while "Soundi" music magazine argued that the album will probably be a mere curiosity in the CMX saga.
