P-MODEL was a Japaneseexperimental/electronic rock band started in 1979 by frontman Susumu Hirasawa. The band has experienced many lineup revisions over the years but Hirasawa was always at the helm of operations. It went through various periods of inactivity, notably from 28 December 1988 to 23 November 1990 and from 11 October 1993 to 1 December 1994. P-MODEL officially disbanded in 20 December 2000, although many of its members continue to release solo albums and collaborate with each other on different projects.
Hirasawa has also released solo work under the similar name "KAKU P-MODEL", primarily the 2004 album Vistoron and the 2013 album гипноза (Gipnoza), with the latter having guest appearances by a former P-MODEL member and a P-MODEL associate.
All videos from THE GREAT BRAIN to HARM HARMONIZER were directed by Yuichi "You1" Hirasawa (Susumu's brother). "FU-RU-HE-HE-HE", "2D OR NOT 2D" and "GRID" were included in "BITMAP 1979–1992"; "Monotone Grid" was included in "PHOTON-3"; "http" was included in "Rocket Shoot"; "Logic Airforce" was included in "LIVE VIDEO Music Industrial Wastes〜P-MODEL OR DIE".
Although P-MODEL has disbanded, many of the members have formed small side projects with each other in similar vein to P-MODEL, including KAKU P-MODEL, PEVO, and Phnonpenh MODEL, as well as their own solo works, Susumu Hirasawa in particular.
