In 2020, Greta created the production company Flims&Films, a creative audiovisual studio for performances, documentaries and projects in the arts.

Her particular interest in music brought collaborations with other artists such as The Black Suns, Manel Navarro, Lucas Delgado, Ilumina Festival, and her latest experimental piece, 'Naturale,' directed for violist Jennifer Stumm and presented at the Delft Chamber Music Festival in 2021. 


Additionally, Flims&Films has  worked with HILTI Foundation and AIM (Academy for the Impact through Music) for the past five years, capturing individual and collective change journeys amongst music teachers and their students in 10 countries and empowering them to use film and photography as drivers of their change narratives.
