Guitar4mation is an international guitar quartet with members from Poland, the Czech Republic, Australia and Austria. 

Founded in 1993, the group saw it's 30th stage anniversary in 2023. The lineup has changed over the years, with two founding members Michal Nagy (Poland), and Martin Schwarz (Austria) still playing in the group. Petr Saidl (Czech Republic) joined in 2003, and Campbell Diamond (Australia) completed the ensemble in 2022. 

Performances throughout Europe have brought Guitar4mation to venues like Konzerthaus Vienna, Concert Hall of Radio Warzaw, Carintischer Sommer, and international Guitar Festivals like Tychy (Poland), Mikulov (Czech Republic), Saitensprünge (Germany). The group has recorded 4 CDs so far, available at Gramola, Vienna. The new album "Our Evenings" with music by Janacek, Halffter, Mompou, Rodrigo and Turina, is in the pipeline. 

Each musician adds different qualities and strengths to Guitar4mation's unique, colorful and intense performance in a concept of democratic music making. 

The group's repertoire is their trademark – only works exclusively arranged for 4 guitars, and only performed by Guitar4mation. The styles range from romantic and impressionistic works from the 19th century to music of very different genres such as commissioned contemporary works written for the ensemble (such as Suite del Dia by Sergio Assad), Latin American music, Jazz and Pop. 

A Guitar4mation concert offers their audience experiences from serious to hilarious, from calm to exciting. Thus, Guitar4mation steps on new paths to explore music unheard on the guitar before, inviting their listeners to moments of intimate quietness, intense rhythms, and the joy of music.
