P-Model (also typeset as P-MODEL and P. Model) was a Japanese electronic rock band started in 1979 by members of the defunct progressive rock band Mandrake. The band has experienced many lineup revisions over the years but frontman Susumu Hirasawa was always at the helm of operations. P-Model officially disbanded in 2000, although many of its members continue to release solo albums and collaborate with each other on different projects.

Timeline

P-Model, as well Susumu Hirasawa through his solo career, have been influential both on musicians, as well as on artists that work on other mediums, with a reputation for having many fans in the manga and anime industries.^[1] Their creative collaborators (and even 6 of the band's members) often started out as big fans of and directly influenced by their work: Berserk mangaka Kentaro Miura has found that listening to Hirasawa's songs has helped him regain focus on the themes of his writing multiple times,^[2] mangaka/anime director Satoshi Kon wrote that Hirasawa's work was "a source of imagination and creativity for me" over the last 20 years of his life,^[3] film director Daihachi Yoshida considers Hirasawa as the creator of "about half of my way of thinking".^[4]

Beyond associates, P-Model and/or Hirasawa have been cited as influences by musicians such as Fukusuke [ja] of Metronome,^[5] Hiroyuki Hayashi of Polysics,^[6] Daoko^[7] (whose song "Welcome to the Parade", from 2012's HyperGirl: Mukōgawa no Onna no Ko, was directly influenced by Hirasawa's worldview^[8]), Toby Driver of Kayo Dot (who claims the album Plastic House on Base of Sky was an attempt to "make [his] version of [Hirasawa's] music")^[9] and Kenshi Yonezu (who has said that a Hirasawa song "changed [his] life").^[10]

The five main characters of the K-On! franchise (Yui Hirasawa, Mio Akiyama, Ritsu Tainaka, Tsumugi Kotobuki and Azusa Nakano) are in a band, share the surnames of late '80s P-Model members and play their respective primary instrument (save for Nakano).^[22][23] All referenced members who are still active have acknowledged the connection.^{[24][25][26][27][28][29][30]} Besides that, P-Model references can also be found on the manga The Sorrow of a Perfectly Healthy Girl^[31][32] and Opus;^[33] as well the anime Sailor Moon, Perfect Blue,^[34] BECK: Mongolian Chop Squad and Space Dandy. In the world of theatre, musician/playwright Keralino Sandorovich [ja] named 2 of his stage plays (Frozen Beach [ja] and Blue Cross) after P-Model songs and 1 (Haldyn Hotel) after a Hirasawa solo song.
