30zona

30zona is a Croatian rap and trap duo from Zagreb: Antonio Martinović and Petar Mateo Glavaš, better known as Shin and Galaš. They are on Muzika-Balkan as a Zagreb act, born of one neighbourhood: both grew up in Kozari bok in the east of the city, where they still live, went to the Vinko Žganec primary school there and, by their own account, have been rapping since the fourth grade.

They have been recording together since 2018, when the video "Ne da mi se ne da" came out. "Samo zovi" with Merula followed at the end of that year, and 2019 brought "Galaš", "Loše navike", "Shin", "200 na sat" and "Keš u krvi". The same year they showed off their quarter, which they call Kozari Bronx, in the YouTube series Kvart priča by Vid Juračić. Among their models they name 50 Cent and Eminem, as well as rappers from the region such as Zimski and Gire.

Their big break came from Serbia. Director Miloš Avramović heard "Galaš" and asked them for a song for his crime series Južni vetar, which closes every episode with a new track. "Pos'o" (2020) made them the first Croatian performers on the show's soundtrack, and with "Divlja igra", filmed in Zagreb's Johann Franck club at the end of 2021, they became the only ones with two.

Their first album, 30, came out in January 2020, followed by the EP 6 (2021), the album 300 (2022), 300 Silver (2022) and the EP S3Z0NA (2025). Along the way they recorded "Kume" with Mimi Mercedez, "Prvak" with Grše, "Blud" with Hiljson Mandela and Merula, "Tokio" with Zimski and "Kune i dinari" with Britni. The playlist holds their records, from "Welcome to K Bronx" to "Legal Illegal".
