"52 Hertz" is taken from "Sequenza", Chloé & Vassilena Serafimova's first joint album to be released in October 2021 on Lumière Noire Records. Musical love at first sight is one way to describe the genesis of the duo formed by Chloé and Bulgarian percussionist Vasilena Serafimova. An impromptu meeting that has since turned into a lasting collaboration, culminating in the release of their first joint album this fall after four years of on-stage and in-studio complicity.
