"Antti Virtaranta is a Finnish bassist and composer. He began his music journey at 17 years old focusing on Jazz music, attending University of the Arts in Philadelphia. Quickly he was introduced to free jazz and experimental electronic music, and this changed everything. He moved to Berlin to join the vibrant scene of improvisers, starting projects with many musicians and developing his own sound. Currently he is focused on expressing his voice in music and sound through composition and improvisation. Using his influences from jazz and rock music and self-taught contemporary music, his musical language is formed. Nowadays, his focus is on concepts and compositions for solo bass and solo electronics, and using non-conventional notations. These ideas develop and are imposed into the small groups (duos and trios) and larger ensembles that he is involved with to create instant composition in his varying projects, which include collaborations with dancers and visual artists, on top of the numerous musicians he works with."
