The ensemble's debut Hopasa (EmArcy Records/Universal, 2013) is comprising the pianist's own compositions, as well as Bucolics (ForTune, 2015), presenting Orzechowski's original arrangements of music by Witold Lutosławski, which soon after its premiere won a place on Jazz Forum magazine's prestigious list of the best Polish albums of all time.

The artist has collaborated with such prominent contemporary music composers as Philip Glass, Steve Reich, and Krzysztof Penderecki.

He has toured with highly esteemed jazz musicians, including Randy Brecker, Avishai Cohen, Victor Mendoza, and Michał Urbaniak.

He has also contributed to the projects of such great figures in the world of music as Adrian Utley of Portishead, Carlos Zíngaro, Agata Zubel, Skalpel, William Basinski, Fennesz, and Krzysztof Knittel.

This monumental work, alluding in its form to Johann Sebastian Bach's 24 Preludes and Fugues, by using as examples short musical structures (Preludes), and equally short but far more complex improvisational creations (Improvisations), artist intends to expound a new way of understanding the notion of jazz and self-expression in music.
