Along with Joachim Kühn, Bronisław Suchanek, Janusz Stefański and Bohdan Jarmołowicz, he took part in the premiere performance of the jazz concerto for violin, symphonic orchestra and rhythmic section composed by Zbigniew Seifert. He has frequently performed with German band Schultzing. Smoczyński is the leader of his own quintet, with which he recorded three albums: Inspirations, Expressions, and Berek. The debut album brought him a scholarship of the Minister of Culture in 2007 and one year later he received a Jazz Oscar.
Within his next project, New Trio (with his brother Jan Smoczyński on Hammond organ and Russian star of the drums – Alexander Zinger), Smoczyński recorded another CD, Simultaneuous Abstractions, which was nominated for the Fryderyk Music Award. Year 2013 saw the release of the trio’s second album Perpendicular Realities.
Smoczyński is the co-founder of Atom String Quartet, the first string quartet in Poland to play jazz. The collaboration resulted in another series of awards and distinctions. Their debut album Fade In and the following one, Places, both received the Fryderyk. In 2015, the band’s double album AtomSPHERE had its premiere, and in 2017 their fourth album Seifert was released. Atom String Quartet has twice been named as the best acoustic band in the Jazz Top readers’ survey of Jazz Forum magazine.
Between 2012 and 2016, Mateusz Smoczyński was playing the first violin part in the legendary American band – Turtle Island Quartet (winner of, among others, two Grammy Awards). He gave over 100 concerts on the most important American stages with that band. In 2013, the quartet took part in the recording of After Blue by vocalist Tierney Sutton, who was nominated for a Grammy Award. A year later, the quartet’s own album Confetti Man, which was recognized by the National Federation of Music Clubs as the best American chamber music recording of the year, had its premiere. Together with Turtle Island Quartet, Mateusz Smoczyński collaborated with Cuban clarinettist Paquito D’Rivera, violinist Michael Doucet, vocalist Nellie McKay, and pianist Cyrus Chestnut.
In 2016, Mateusz Smoczyński founded a duo with one of the greatest cellists in the world – Stephan Braun. A year later, the Zbigniew Seifert Foundation released Smoczyński’s first classical solo violin album, Metamorphoses.
