Together with the spiritus movens of the orchestra, Bojan Cvetrežnik, the violinists Klemen Bračko (member of Godalika) and Matija Krečič form the core of the band. Other musicians featured in the orchestra are (or have been) Danijel Černe a.k.a.

Of the 100 hundred foreign guests, one could name Jean Christophe Gairard (FR), Emilio Castiello (FR), Rina Kaçinari (XK) and Ida Meidell Blylod (SE). Ida has been especially involved in the orchestra and has together with them led music workshops. She and some of the members of the orchestra also have a band Ida & Other Bears (or, occasionally, Ida & Symbolic Bears).
Symbolic Orchestra has been incessantly touring around Slovenia and the world. They have had numerous gigs with the group Terrafolk and have also collaborated with the famous Slovene poet Svetlana Makarovič.
Besides the countless gigs on streets all around Europe, the orchestra has played at Layer House, One Music Salon, Cankarjev dom, Cultural and Congress Centre, Prulček bar, Celica Hostel, Kosovel Culture House Sežana, the Slovene Philharmonic, the Slovene National Theatre Drama Ljubljana, Zlati zob Ethno club, Kamfest, HISTeRIA Festival, Sanje ('Dreams') Festival, Lent Festival, etc. They have also repeatedly taken the stage in France (for example, at Studio de l’ermitage), Italy, Croatia, and Belgium.
The Symbolics (as they occasionally style themselves) are involved in different workshops (both for children as well as grown-ups), which they sometimes organise together with One Music Society. Though the collective has not been very active in publishing their music, they have released an album on the One Music Society's label.
