Geek Music is a Japanese group that formed in Tokyo in the early 2000s. The band includes vocalist Yuko Kurose, guitarist Masatoshi Mashima, and bassist Dai Takase. They built a following with a mix of electronica and rock that appealed to anime fans.
In 2018, their song "Canzoni Preferite" was used as the ending theme for the anime series JoJo's Bizarre Adventure: Golden Wind. It became widely known as the Torture Dance Song and gained millions of views online. The track appears on their compilation JoJo's Bizarre Adventure Golden Wind: Canzoni Preferite.
Some listeners raised questions about similarities between the Torture Dance Song and earlier work by another band, Superfly. Mashima addressed this by stating the song was original. Their catalog also includes the track "Day 'N' Nite."
