In Sarajevo, Napredak's traditional Easter concert was held: The audience enjoyed performances of classical music.

The church was filled to the last seat, and the audience had the opportunity to enjoy a performance by the renowned ensemble Camerata Garestin, featuring soloists Ivana Lazar (soprano), Krešimir Lazar (cello), Krešimir Has (harpsichord), and Stjepan Nodilo (traverso flute and oboe). The concert, in the spirit of Easter, presented a curated program of classical music and showcased the ensemble's rich cultural tradition.

Incidentally, the Camerata Garestin ensemble brings together leading Croatian vocal and instrumental performers of 17th and 18th-century music. It was founded in 2008 on the initiative of Varaždin cellist Krešimir Lazar, along with co-founders soprano Ivana Lazar, flutist Danijel Bošnjak, and harpsichordist and organist Krešimir Has.

With their extensive experience, the ensemble members contribute to Croatia's cultural and artistic life, and their work has been repeatedly recognized and supported by the Ministry of Culture.

Special emphasis is placed on Croatian musical heritage, including works by Ivan Marko Lukačić, Vinko Jelić, Gabriel Puliti, Tomaso Cecchino, and Ivan Šibenčanin.

The ensemble performs on replicas of Baroque instruments, and its name reflects the medieval name of the city of Varaždin—Garestin. The ensemble's programmatic direction focuses on thematic concert projects, performing masterpieces by European and Croatian masters of the High Renaissance, Baroque, Galant style, and early Classical period.
