TRANSMUSIC COMP., former Czechoslovakia's most original ensemble for experimental music, was formed by Milan Adamčiak, Peter Machajdík and Michal Murin as an open group of two or more members - professional and non-professional musicians, composers, visual artists, dancers, performers, and authors of music and audio-visual projects in October 1989.
​  
The founding members of ​TRANSMUSIC COMP. began their activities with a series of music performances connected with individual and collective exhibitions of contemporary Slovak and Czech artists, particularly non preferred, peaking in early 1990s. The first performance of the ensemble took place at the exhibition of the artists' group Gerulata in Rusovce near Bratislava, Slovakia on 15 October 1989. Further performances were held at events such as Querdurch (Feb 1990), Art Against Totality, Six "Fortitude" Artists, Juraj Meliš's retrospective, an exhibition of painter Vladimír Popovič, the Konvergencie Festival, Festival of Alternative Art and elsewhere.
The activities of TRANSMUSIC COMP. led to the foundation of the SNEH society in January 1990. 

The repertoire of TRANSMUSIC COMP. has included works for conventional instruments, live electronics, computers and tape music by group members (Adamčiak, Machajdík, Murin, Burlas, Ďuriš, Prokop, Horváth), graphic scores (Earle Brown, Anestis Logorhetis, Herman Rechberger), Fluxus music and events (Georg Brecht, Ben Patterson, Thomas Schmitt, Ben Vautier, Yoko Ono), instrumental theatre and acoustic performances, music for found objects, sound objects and installations, free improvisations and intermedia.

TRANSMUSIC COMP. has recorded a number of TV programs and music for short films, and regularly collaborated with the Experimental Studio of Slovak Radio. 

After Adamčiak's death in 2017, TRANSMUSIC COMP. performs mainly as a trio (Machajdík, Murin, Prokop) with guests (dancers, visual artists etc.). The most recent performances of TRANSMUSIC COMP. have taken place at experimental music festivals and exhibitions in Prague, Bratislava, Ostrava and other places of former Czechoslovakia.
