Bandleader Susumu Hirasawa, feeling the group was in a state of crisis, distanced P-Model from the genre, trying to drive trend followers through rebellious episodes, and replacing their colorful clothing and equipment for a muted getup (black, white, gray and blue).

[1] Bassist Katsuhiko Akiyama's creative position was in an opposite direction to where Hirasawa wanted to take P-Model, so he was fired from the band, and his songs were not played anymore.

Kikuchi did not formally join the band while Potpourri was being recorded, leading Hirasawa and keyboardist Yasumi Tanaka to play bass parts on the album, each doing the songs they wrote.

[2] Potpourri has a harsher and more off-putting sound than previous albums, with P-Model employing different instruments and experimental recording techniques.

All tracks are written by Susumu Hirasawa, except where noted"film" contains an interpolation of Yoshiko Ishii's [ja] 1959 translation (originally performed and recorded by Ishii alongside the Dark Ducks [ja]) of the traditional French children's song "J'ai Perdu le Do de Ma Clarinette" [ja] (クラリネットをこわしちゃった, Kurarinetto wo Kowashi Chatta, French: 'I Lost My Clarinet's C', Japanese: 'I Broke My Clarinet'), believed to date no earlier than 1800.
