Often lauded as one of the leading figures of the Czech jazz scene, David Doružka has been active as a professional musician from the age of 14, having played concerts all over the world, collaborated with many of today’s leading musicians, and having spent extensive periods in the cities of New York and Paris. After recent collaborations with jazz icons Lizz Wright, Jeff Ballard or Hilmar Jensson, Doružka teamed up with flutist Robert Fischmann and drummer Martin Novák to explore a sound which is less jazz-centered and more world-oriented. The core of this unusually sounding ensemble is the legacy of Jewish music with its many facets that have evolved on various continents over the centuries.

However the trio takes great liberties in incorporating all of these elements and so it easily happens that traditional Chassidic chants are followed by metalcore passages and melodies from Medieval Spain are heard next to sounds inspired by the contemporary New York downtown scene. Their present debut album is entitled Gilgul, meaning "cycle" in Hebrew. Jewish music is nothing new to members of the band as they have previously collaborated with Israeli musician Yair Dalal and American multi-instrumentalist Alan Bern among others and Doružka’s earlier CD Autumn Tales (2016, Animal Music) awarded the Czech Music Academy Angel Award for the best jazz album of the year bears influences of both Ashkenazi and Middle-Eastern music.
