The following is the solo discography of Susumu Hirasawa, Japanese musician and composer. Since the beginning of his professional activities in 1973, Hirasawa has produced a prolific number of recordings, with a constant stream of releases since 1978, under his own name as well as multiple bands and side projects. See Mandrake (Japanese band), P-Model and Shun (band) for more output.
Besides the works listed below, he also contributed pieces for the anime X-Bomber (see "other projects").
From 1983 to 1990, Hirasawa worked on various commercials. Unlike most of the soundtracks listed above, Hirasawa undertook these less out of artistic interest and more out of financial necessity. Outside of those included on Model House Works, most of these jingles have never been officially released and not precisely identified—by Hirasawa or his fanbase—but among his clients were companies like Denon, Honma Golf [ja], Japan Tobacco, Kirin, Mazda, Mizuno, NTT, Pip Fujimoto [ja] (rearranging another musician's jingle[13]), Rado, Snow Brand Milk Products, Tsukuda [ja], TV Asahi, Unicharm and Volvo.[4] After he acquired an Amiga, he took on a handful jobs making both music and CGI with Takara, Itoki [ja] and HTB.[4] Beyond broadcast work, he also contributed to installations like the Optic Fiber Clock (located on the Bellvia mall near Chino Station, plays a unique Hirasawa song centred on bird chirps once an hour 10 times a day; originally featured karakuri puppet birds that moved in sync with the chirps), Tokai Bank automated teller machines, a closing time tune for a Shinjuku cake shop and synthesizer sound effects to make a Korakuen Amusement Park rollercoaster scary.[4]
Collections of studio recordings of rearrangements and/or original songs made for live shows.
Hirasawa has semi-regularly uploaded snippets of album tracks ever since the start of professional activities online, and after going independent, regularly releases one track from an album free of charge, effectively serving the same purpose of a single in promoting the parent album.
"Hybrid" releases, containing both solo and P-Model material, are listed elsewhere (see "live albums" and "videos").
