Atom String Quartet is one of the most intriguing string quartets in the world, and also one of best Polish jazz bands. The group combines the capabilities of a string quartet (two violins, viola and cello) with improvisation in its broad sense. The set of instruments of a chamber music ensemble, which is most classic and firmly established in music tradition, enables the artists to search for new sound and formal achievements. It is difficult to define, in an explicit way, the music style of the group. Its music output, besides jazz, shows sources of inspiration coming from Polish folk, music of various regions of the world, and also contemporary and classical music. The quartet was established in Warsaw in 2010, and is created by the violinists: Dawid Lubowicz and Mateusz Smoczyński, the violist – Michał Zaborski and cellist – Krzysztof Lenczowski. All of them graduated from Warsaw Frederic Chopin University of Music. Since winning the Grand Prix of the 13th Bielska Zadymka Jazz Festival in 2011, the band constantly performs at the greatest music festivals of the world, such as: Berliner Jazztage, Jazz Baltica, Leipziger Jazztage, Cairo Jazz Festival, Katara European Jazz Festival, Festival Veranos de la Villa Madrid, Gaume Jazz Festival, Manchester Jazz Festival, Jazzycolors Festival Paris, Salzburger Festspiele, Jazz Jamboree and Solidarity of Arts. Atom String Quartet is also the first and only Polish group that played at the European jazz fair jazzahead! in Bremen.
