Trzaska was the co-founder of the yass group Miłość, one of the mainstays of the so-called yass scene. The band collaborated with Lester Bowie and Tomasz Stańko, among others.
For Trzaska year 2003 was abundant in musical inspirations and meetings. While in Ukraine, he recorded the album Andruchoid along with Jurij Andruchowycz, a distinguished Ukrainian writer and poet. In 2005 Trzaska’s Scandinavian trio Trzaska/Friis/Uuskyla was joined by Peter Brötzmann. Thus, North Quarted was formed and the album Malamute was recorded. The capstone of Trzaska’s international career was the invitation to Ken Vandermark’s Resonance, where he plays until today.
In the first decade of the 21st century Trzaska turned to traditional Jewish music, partially because of his Jewish roots. This resulted in forming the band Shofar with guitarist and composer Raphael Rogiński and drummer Macio Moretti. So far the ensemble recorded three albums: Shofar (2007), Ha-huncvot (2013) and a DVD recording of a live concert at Powiększenie club.
In 2008 Trzaska formed another band – clarinet quartet Ircha (Wacław Zimpel, Paweł Szamburski and Michał Górczyński).
