Kalevi Hämäläinen Group is a modern jazz ensemble that was established in Savonlinna in 2015. After thorough preparation, band's debut album First Days of Summer was published in spring 2020 via Eclipse Music.

Having their main influences in modern fusion, songs of the band have also elements from progressive rock and pop music. Positivity and exuberance characterize the music of Kalevi Hämäläinen Group. In addition to spacious melodies and joyful harmonies, band's music contains surprise elements, and different atmospheres are consolidated by versatile application of sounds.

The unique sound of the group has appealed to jazz- and prog-oriented crowds alike. Several tracks from the debut album have been broadcast both in Finland and internationally, and the same applies to many positive album reviews.

In September 2021, new music came out from the group as they released a digital single called Arcade – an upbeat fusion song that contains the atmosphere of traditional amusement park arcades with their rush and flashing colors.
