About Jari Mäenpää
Jari Mäenpää (born 23 December 1977) is a Finnish singer, guitarist, multi-instrumentalist and songwriter. He is the founder of the melodic death metal band Wintersun for which he sings and records the majority of instruments except the drums. Before forming Wintersun, Mäenpää was also known for his role in the folk metal band Ensiferum, which he joined in 1996 after leaving his prior band named Immemorial. Wintersun was initially planned as a parallel project alongside Ensiferum, but in January 2004 he was forced to leave Ensiferum due to clashes between their touring schedule and the studio recording time he had booked for Wintersun. In 1997, Mäenpää had to put his musical career on hold to take part in Finland's compulsory military service. In an interview, Mäenpää admitted he disliked the time he spent in the military and suspects it's where he acquired tuberculosis. Jari was also a member of the band Arthemesia, and participated in Kimmo Miettinen's side project Lost Alone.
