Goran Krmac is a performer, composer, and arranger active in the current millennium. He finds his main creative expression as a virtuoso tubist with jazz, folk, and classical influences. His foremost endeavour is Planetarium, a solo tuba/real-time electronic sound manipulation performance which combines live music performance with soundbites from the diary of a deep space exploration mission’s crew member who, by dealing with novel experiences, treacherous and fascinating alike, fulfills a voyage of self-discovery. Through a custom-built software-hardware interface, Goran Krmac turns real-time sound manipulation into an extension of his instrumental performance. Goran is also featured on releases by established Slovenian jazz, pop, and folk artists, such as Kaja Draksler, Robert Jukič, Big band RTV Slovenija, Boštjan Simon, Rudi Bučar, Janez Dovč, and Sounds of Slovenia, to name a few. Also active as conductor and arranger, Goran is the artistic leader of Big band Cerknica.
