Polysics is a Japanese techno/electronic band from Tokyo, who dubs its unique style as "technicolor pogo punk". It was named after a brand of synthesizer, the Korg Polysix. The band started in 1997, but got their big break in 1998 at a concert in Tokyo. They create high energy music, fusing conventional guitar music with synthesized and computer generated sound to create a unique mixture of punk and synthpop heavily inspired by the American bands Devo and The Tubes, as well as Japanese bands such as P-Model and Yellow Magic Orchestra. Their song lyrics often consist of Japanese, English, or just downright gibberish. The band has been noted for their extremely energetic live performances and their wild gimmicky outfits, notably their straight-bar sunglasses and trademark orange boiler suits stamped with a simple "P".

Sony Music Entertainment (Japan) Inc. , often abbreviated as SMEJ or simply SME, and also known as Sony Music Japan for short, is a Japanese music arm for Sony. Founded in 1968 as CBS/Sony, SMEJ is directly owned by Sony Group Corporation and is operating independently from the United States-based Sony Music Entertainment due to its strength in the Japanese music industry. Its subsidiaries include the Japanese animation production enterprise, Aniplex, which was established in September 1995 as a joint-venture between Sony Music Entertainment Japan and Sony Pictures Entertainment Japan, but which in 2001 became a wholly owned subsidiary of Sony Music Entertainment Japan. It was prominent in the early to mid '90s producing and licensing music for animated series such as Roujin Z from acclaimed Japanese comic artist Katsuhiro Otomo and Capcom's Street Fighter animated series.
