Ulher originally studied in visual arts, an area which still exerts a strong influence on her music. Since moving to Hamburg in 1982 she has been involved in the City’s vibrant free music scenes and developed a highly distinctive musical language of her own. Her work centres on extending the sonic possibilities of the trumpet to explore the shapes, textures and colours found beyond the instrument's open tone, and, more recently, the relationship between sound and silence. She performs solo and with her working ensembles, collaborations with dancers, visual artists, composers and one-time collaborations with musicians from around the world.

Collaborations with Ute Wassermann, Lucio Capece, Gino Robair, Bill Hsu, Leonel Kaplan, Christoph Schiller, Heddy Boubaker, Chris Heenan, Gregory Büttner, Forbes Graham and the Stark Bewölkt Quartet (with Michael Maierhof, Heiner Metzger and Gregory Büttner) amongst others.
