Marcin Józef (Martino Giuseppe) Żebrowski – composer, violinist, singer (bass) and teacher – is one of the most outstanding representatives of the Polish musical culture of the 18th century. This is clearly confirmed, on the one hand, by his preserved works, and on the other, by the fact that his works were printed – as one of the few Old Polish composers – outside the territory of the Kingdom of Poland. In 1757 and 1758, the series of six sonatas a Due Violini & Basso and Sinfonia in E flat were published by Johann Julius Hummel in Amsterdam. The above-average, compared to other Polish composers of that period, talent of the Żebrowski, as well as his highly original creative invention and the variety of cultivated forms are perfectly demonstrated by this monograph recording, the second in the catalogue of the National Forum of Music in Wrocław devoted to this composer.
