On the year of Landsale's release, the technopop boom was reaching critical mass. Feeling in a state of crisis he 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). At one concert, a leaflet titled "The Point of Coming to a Concert" was distributed while Landsale was looped endlessly through the PA system; the band did not play until the concertgoers started an uproar which led to a backlash against the band.

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. He was replaced by high school sophomore Tatsuya Kikuchi, a student of Hirasawa's at the Yamaha Synthesizer School. Kikuchi did not formally join the band while Potpourri was being recorded, leading Hirasawa to play all bass parts on the album.

Potpourri has a harsher and more off-putting sound than previous albums, with P-Model employing different instruments and experimental recording techniques. Guitar is more prominent than the keyboard-centric albums from before, leaving synthesizers to go almost unused. Hirasawa incorporates greater antagonism into his vocals, sometimes to the point of screaming them.

The album alienated P-Model's fanbase, leaving only a core audience that would persist with Hirasawa throughout his career.

All tracks written by Susumu Hirasawa, except where noted.

In all releases of the album, the titles consisted of Japanese characters are rendered only through the characters, except for title track, which is rendered as "potpourri (ポプリ)".
