According to the J-card, this is the first Ohkami No Jikan album and they "concentrate on the heaviness of minimal noise". Unfortunately, as far as English is concerned, it doesn't reveal who amongst the revolving membership are present for the recording. Obviously, Asahito Nanjo is here but all else would be speculation.
C58 released on La Musica Records in 1999. It's LA-026 btw.
