The Club of Electrical Engineering Students (KSET) and the Zagreb collective 42Hz are joining forces to bring a night dedicated to bass music to AKC Attack on February 13. The headliner of the evening is the duo TRAKA, with support from Zagreb-based DJ Babilonska and residents of the 42Hz collective.
TRAKA is a project founded in Belgrade that merges electronic music, graffiti, and visual art into a unique sound that breaks genre boundaries. Formed in Belgrade and now operating between Europe and the USA, they deliver raw, rhythm-driven production inspired by sound system culture, grime, and dubstep.

Known for their collaboration with the YUKU label and a distinctive visual identity, TRAKA creates music for the dancefloor – from 140 BPM halftime rhythms to energetic breaks and tech-breaks. Their sound reflects years of immersion in underground scenes and a passion for bass music in all its forms. In 2025 and 2026, they have a series of notable releases on YUKU, System108, FKOF, Satellite Era, and RENRAKU, along with performances across Europe and the USA.
Babilonska is a Zagreb-based DJ whose sets blend eccentric jazz, hip hop beats, and psychedelic soundscapes with noisy riffs from the depths of hell. Her sound leans on heavy bass, doom atmospheres, and diverse rhythms from around the world.
For eight years, she curated ZEZ Festival, dedicated to experimental music and sound art, and in 2025 she launched onkraj – a series of club nights, concerts, and listening sessions devoted to the collective experience of listening. She has performed at Fusion Festival, at Hamburg clubs MS Stubnitz and Hafenklang, at the first Croatian Boiler Room event, and has shared the stage with names such as The Bug, Slikback, Blawan, Coco Bryce, and DJ Travella.

42Hz is a Zagreb collective building its underground universe through bass frequencies. Formed spontaneously out of friendship and a shared passion for drum ’n’ bass, bass, and related styles, the collective consists of Bansha, Bør-T, Kocka, pilif, Spooky M, and updxg – all connected through KSET.
At this event, pilif – who loves fat basslines, fast breaks, cheeky bootlegs… and alliteration – will be behind the decks. He gained his first DJ experience through KSET’s Disco section and, over time, began playing independently around Zagreb and beyond. Recently, he has been increasingly booking both bands and DJs for KSET and ZEZ.

He will be joined by SpookyM, a Zagreb enthusiast of the British sound whose sets are dominated by amen breaks, deep basslines, and broken rhythms. When SpookyM isn’t playing in clubs, he curates selections on Radio Student.
