Antonio has been in music since elementary school when he sang in a hardcore punk band. From this, the small underground record label Progressive Attack developed. In addition to distribution and publishing, he also started a fanzine of the same name and participated in the organization of concerts. It was from those first attempts at playing music that he became interested in graphic design. The first works did not survive, but they resulted in future collaborations. Thus, Antonio has been cooperating with the Ljubljana publishing house Moonlee records and Rijeka’s Distune Promotion for over 10 years, and through Radnja he participates in a number of other projects. He designs visual identities for organizations and festivals such as Impulse Festival, Žmoht Fest, Moonlee Records, Distune Promotion, Hangtime Agency, Rock Svirki and London’s State51, as well as records for several bands, including Repetitor, Bernays Propaganda, Seine. Of course, he enriches his entire oeuvre with recognizable concert posters in all countries of the region. In 2018, the American band Algiers used the design of the poster for the Rijeka concert as the band’s official visual (especially for the distribution of music memorabilia). Although music is an important part of everyday work, Antonio works for non-governmental organizations as well as commercial customers.
