Signum Quartett presents the album the earth trembled, recontextualising the visionary string quartets of Leos Janacek alongside the striking String Quartet Op. 8 by Vitezslava Kapralova. Janacek's lifelong engagement with folk traditions shaped these works profoundly; he lays bare an extraordinary spectrum of feeling, exposing the innermost reaches of his psyche with an almost unsettling immediacy, music in which the earth really does tremble. Set against this, Kapralova's quartet offers balance: a strikingly youthful yet assured voice emerging from the same cultural milieu, opening an equally compelling emotional range. Interspersed throughout are fragments of Janacek's folk song arrangements and intimate miniatures from his album for Kamila Stosslova, whose absent voice subtly haunts the programme, weaving a fragile, imagined narrative between the works. This recording offers a fresh perspective on works that have accompanied the Quartett for many years and remain among the most emotionally overwhelming in the repertoire. Signum Quartett is frequently hailed as one of the most adventurous and outstanding ensembles of today. This is the quartet's fourth album with PENTATONE, after the Schubert cycle including Aus der Ferne (2018), Ins stille Land (2020), and Lebensmuth (2023).
