psc trio was formed in late 2016 to combine the worlds of jazz, rock and classical music via original compositions and arrangements.

the compositions are built around the interplay of jazz harmonies, complex rhythms and extensive improvisation; many of them are composed in the "long-form" compositional style of classical music.

the arrangements take well-known songs from pop, rock and jazz and re-build them in a manner similar to our original compositions. the arrangements include songs by michael jackson, guns n' roses, silvio rodriguez, duke ellington and others.
