Ari Koivunen is a Finnish heavy metal singer who rose to fame as the winner of the Finnish singing competition Idols in 2007. He was the vocalist of the Finnish heavy metal band Amoral from 2008 to 2017. Beside he has worked with many musical projects already before and also after Amoral disbanded.

Amoral was a Finnish heavy metal band from Helsinki, formed in 1997. They played technical, progressive, melodic, hard rock-oriented metal. The band's fourth album was an about-turn, replacing the dominance of quirky death metal with an exemplary display of riff-driven, heavy, yet melodic power groove and the occasional sing-along chorus. Amoral performed extensively in bars, clubs, festivals and other venues in Finland, Europe, Japan, China, Philippines and the US. The band split up in 2017 after 20 years together.
