Als an interdisciplinary group, Trio Wellenbad invents musical formats for public swimming pools: computer science, architecture and composition come together in the trio members Joseph Baader, Nathalie Brum and Vincent Stange to perform in a musical and wet way.

Since 2023, Trio Wellenbad has been playing electroacoustic music in sports and thermal baths, which can be heard underwater via special loudspeakers. Beginning with concerts and installations at the Frankenbad Bonn and the Münstertherme Düsseldorf, further performances followed in Aachen, Berlin and Innsbruck. For the Beethovenfest Bonn 2025, Trio Wellenbad developed a sound and video installation and a world premiere with trombone and saxophone at the Frankenbad Bonn.
