This album marked the first appearance of drummer Akira Jimbo, who replaced Takashi Sasaki that same year.

In addition to the technical and detailed ensemble shown in their past two albums, their high performance in the live recordings, and the sophisticated drumming techniques of Akira Jimbo, have earned them even higher praise than ever.

The jacket of the first edition, released in 1980, featured a caricature of the members in extreme colors, standing against a backdrop of crimson flames.

This original jacket has received major criticism, even from Akira Jimbo's mother.

However, from the re-press version, the cover was changed to a more subdued color scheme featuring an illustration of lightning falling on the sea surface.
