Mikolaj Trzaska is one of Poland's leading free jazz musicians. He has toured and recorded with his Clarinet Trio (with Ken Vandermark and Waclaw Zimpel), Peter Brotzmann, Joe McPhee and Lester Bowie, among many others. He is also a member of ken vandermark's Resonance Ensemble.

“Mikolaj's sound on alto is mesmerizing, even at his most lyrical there's the inner tension in the timbre, you could hide entire planets in there, even at his most expansive and screaming, there's something intimate and emotional to what he plays.” – (Free) Jazz Alchemist
