Shun (旬, later known as Syun) was a Japanese experimental sampling unit created by Susumu Hirasawa.
In 1983, Susumu Hirasawa's band P-Model had their Another Game album delayed four months by their label Tokuma Japan Communications, who demanded the group redo the lyrics of the song "Atom-Siberia", claiming they encouraged discrimination.
After this, P-Model broke their contract with Tokuma and created the "Another Act" project, where the group would release records with compositions made independently by each member in styles different from P-Model.
After the fourth Shun album in 1987, the project was put into dormancy until 1994, when Hirasawa re-branded it as Syun, a label to release some of his less commercial works.
No more albums were released under the Shun/Syun name after 1996, although Hirasawa continued to use the sounds that originated in Syun albums, most notably in his soundtracks for the adaptations of Berserk and the works of Satoshi Kon.
