About

My name is Esa Onttonen (b. 1975) and I’m a composer and guitarist living in Helsinki, Finland. I mainly work in the field of jazz and improvised music but I’ve also played rock riffs on electric guitar and written scores for classical orchestras.

I’m a co-leader of groups Gourmet and Gnomus which have released a total of ten albums and performed in about dozen countries. The latest releases to feature my music are KOLIZIO’s Universala albumo (2024), which includes my composition “Getting Paid (For What You Do)”, and Gourmet’s Symposium (2025).

“Esa Onttonen is the epitomal erudite whizz-kid; I don’t know of any area in the modern day musical milieu to which he isn’t ultra-savvy. Pass him by at your peril.” —Michael Gibbs

I have written commissioned compositions and arrangements for orchestras such as Finnish Radio Symphony Orchestra, UMO Jazz Orchestra, KOLIZIO, Virtuosi di Kuhmo, St. Michel Strings, Uusinta Chamber Ensemble, Kaartin Seitsikko, Jyväskylä Big Band, Ebeli Big Band and Avanti! (with Badu Ndjai), and soloists Jukka Gustavson, Mikko Innanen, Jukka Perko and Tomasz Stanko.

As guitarist I have played and recorded with my own co-led groups Gnomus and Gourmet and as sideman with Halme Prospekt and many others. In 2017 I began to develop a solo project for electric guitar and computer-based processing, with the debut performance taking place in La Villa Des Arts, Paris in May 2017.

My latest and largest project since 2020 has been developing an application for live composition in improvisational contexts. There’s also now an improvisation group, Esa Onttonen Labra, that uses the app.
