The Berlin Improvisers Orchestra (Ber.I.O.) was founded by Saxophonist Anna Kaluza in June 2010, with the help of “accoucheurs” Alison Blunt & Ricardo Tejero from the London Improvisers Orchestra.



The musicians conduct pieces using  hand signals based on the conduction concept of American composer and improviser Butch Morris, these gestures are used and expanded upon by improvising orchestras worldwide.
