Jyväskylä Big Band has become known as a promoter of new Finnish music. JBB has been collaborating with Finnish composers since 1998, and the Ensikäsityksijä concert series is an excellent example of a successful collaboration. JBB performs in Finland and internationally, and many of the band's musicians have become top names in Finland. Conductor Ilkka Mäkitalo has been the orchestra's conductor and artistic director since 1995.
