The duo Ester Poly consists of Martina Berther (electric bass, voc, Zurich) and Béatrice Graf (drums, voc, Geneva). The band’s music moves between psychedelic rock, punk, and new wave and deals with mostly political content. Since its creation in 2013, the duo has given over 160 concerts in Switzerland and abroad (including France, Germany, the Czech Republic, Benin, Russia, Italy, and Australia). They have performed in everything from large clubs and festival stages (PROGR Bern, Bogen FZurich, B-Sides Festival Lucerne, Stadtsommer Zurich, Bad Bonn Kilbi, Jazzfestival Willisau, among others) to small DIY concerts, solo parties, and demonstration parades (women’s strike 2019).
