Karkador is the sixth album by the Japanese electronic rock band P-Model, and the first where frontman Susumu Hirasawa was the sole remaining founding member.
He was replaced by Yasuhiro Araki, a huge fan of P-Model who had formerly played in a punk rock band.
In addition to Hirasawa's journal, P-Model used songwriting contributions from their keyboardist Shunichi Miura and bassist Tadahiko Yokogawa.
He wanted Karkador to sound "underground", feeling that in-house engineer at Gok Studio Yoshiaki Kondo was best for the job.
[1] Miura had doubts as to the direction that P-Model was taking and left the band[3] alongside Yokogawa, who felt that touring in support of the album was too rigorous.
