Orrantia is an artist interested in the transformative power of performance. He can wear many hats, from performing on stage to teaching and working on innovative formats for improvisation and theater. Building his practice over the last 15 years, he is well known for working with elements of performance and visual arts, including painting, and drawing. His innate curiosity in the field of improvisation led him to create and co-direct the PICNIC theatre group, as well as the MonkeyFest International Festival, currently in its ninth edition. A non-stop series of shows and workshops has him travelling around the world; recent highlights include participation at the Improvember Improtheaterfestival in München, Shows and workshops in Brno, workshops series in Vienna and the world premier of his latest solo show, The Fortune Teller. He is also known for his work with Speechless, a wordless show driven by musical scores that has been delighting audiences in the Americas, Europe and the Middle East.

The fantastic adventure of performing has taken Orrantia on a journey where he explores different specialties including mask, eccentric performing, physical theatre, Meisner, clown, bouffon, interactive performance, melodrama, phonetics and improvisation. On this path he studied with mentors such as Keith Johnstone, Avner Eisenberg, Adrian Danzig, Daniel Stein, Dody DiSanto, Aitor Basauri, John Britton, Patti Styles and Ariel Guitierrez among others. This research took place at renowned spaces such as The Celebration Barn in Maine, USA, and festivals like Impro Amsterdam and the Berlin Impro Festival.
