Josef Kowalsky is a progressive fusion project led by Amsterdam-based bass player Marta Golka. The name of the band was inspired by the main character of Franz Kafka’s iconic novel The Trial. In their music, progressive rhythms, mellow harmonies and improvisation collide, forming gripping musical landscapes that show influences from a variety of different genres such as jazz, progressive metal, pop or Carnatic music. They draw inspiration from artists such as Ben Wendel, Tigran Hamasyan or Animals as Leaders.

The band released their debut EP Flares in October 2023 and a single Kelpie’s Dance in April 2024. The recording of the first was supported by Amsterdams Fonds voor de Kunst (Amsterdam Fund for the Arts) and a successful crowdfunding campaign on Both releases got positive reception and appeared on several radio stations including a.o. Radio Nowy Świat (New World Radio) and Radio Opole.
