Brothers Tessela and Truss are among the most recognizable names in underground dance music of recent years, working with the sounds of British club traditions, from Tessela’s hardcore-informed breakbeats to Truss’s deadly industrial clamor. After working for some time as TR\\ER, they’re rolling out a new project Overmono, bringing a live performance to Kraków on the back of a new EP for XL Recordings called “Arla”.
