Teemu Takanen (b. 1984) is a Finnish jazz saxophonist and composer/arranger. He conducts Savonlinna Big Band and ESA Jazz Orchestra and works a freelance musician, mainly with his own band Takatonic. Takanen is strongly influential in eastern Finland, particularly in the province of South Savo, where he performs, teaches and gathers local jazz musicians together. As a result of this work, South Savo’s own jazz orchestra, ESA Jazz Orchestra, was founded in 2010.
