Founded in 2021 by brothers Fabian and Tobias Köninger and singer Benjamin Frenzel, Yeast Machine, featuring Jonas Bischof on drums and Marcel Gundlach on bass, quickly became a fixture in the southern German rock scene. Following initial studio live sessions and the EP Rise of the Yeast (2023), their debut album SLEAZE was released in April 2024 via Tonzonen Records.

Yeast Machine is also an experience live. Whether in small clubs or at festivals – the band plays with unbridled energy, sweat-inducing, and close to the audience. In 2023, they toured Germany, Austria, and Switzerland, sharing the stage with acts such as Grandson and Pariahlord.

With their debut album SLEAZE, Yeast Machine made a clear statement: honest rock with heart, grime, and attitude – handcrafted, powerful, and full of life.
