This quartet is a dose of strong structural free jazz and a clash of several cultures in contemporary improvised music. The basis for improvisation are the compositions of all the musicians. It’s uncompromising, passionate free, but the music is more concentrated, the structures are more spatial and at the same time more abstract, richer sonoristically. Joe McPhee – a multinustrumentalist (also a composer and poet) started his career as a musician by learning to play the trumpet in a school ensemble. At the end of the 1960s he himself began to learn to play the saxophone, experimenting with solo recordings. Perceived as a jazz avant-garde, he was eagerly invited to take part in the ultra-modern projects of outstanding innovators. Mark Tokar – a bass player living permanently in Lviv, a leading representative of improvised music in Ukraine, who often cooperates with Polish musicians. Klaus Kugel – studied at the Jazz School in Munich. Since 1989 he has taken part in many projects with the outstanding Lithuanian saxophonist Petras Vysniauskas. Mikołaj Trzaska – saxophonist, bass clarinettist, composer, in 1988-1991 studied fine arts. He grew up on the basis of yassu, an artistic and social movement which at the turn of the 1980s and 1990s rebelled against the ossification of the national jazz community. Trzaska was a co-founder of the most important yassu formation – the legendary Love and (still active) Łoskot. Although the impetus of yassu expired many years ago, he became a leading figure on the Polish improvised scene. After the yass period, he recorded several concentrated and quiet albums with the Oleś brothers. He also accompanied poets: To Świetlicki and Andruchowycz, he created music and literary projects with Andrzej Stasiuk. Today he is the leader of the international Volumen trio, a member of, among others, the Bassisters Orchestra and Shofar – performing Jewish music. However, Above all, he realizes himself on the grounds of radical free jazz, cooperating with dozens of world famous free improvisers.
