​WERO, born Roman Weyermann (May 23, 1996), is a DJ and producer from Bern, Switzerland. He is known for energetic sets with depth, emotion, and character. His musical journey began in the studio on April 2, 2023, and has since rapidly evolved into a distinctive signature within the electronic music scene.​ Together with three close companions, including DJ and producer MATHIEU, he founded the music and record label FOURSIDE. Since then, he has performed at numerous national events in front of thousands of people and released multiple tracks on the label – consistently building a unique vision beyond the mainstream. ​His sets are more than just music – they are journeys: emotional, driving, and hypnotic. Pumping basslines, distinctive synths, and seductive vocals merge into a sound with strong recognition value. Stylistically, WERO moves between Melodic Techno, Indie Dance, and powerful Tech House. ​He has already performed on major stages and festivals, including WeLoveTechno alongside Joris Voorn, the Wankdorf Festival Bern with TH;EN, and the FOURSIDE Invites event series with YUBIK (AFTERLIFE Records). Along the way, he has connected with international artists such as Lilly Palmer, Korolova, and Paradoks. As a producer, WERO is also gaining attention: with tracks like «Get High,» «Safe and Sound,» and his solo debut «Red Lights», he has already reached several thousand listeners worldwide.​ Beyond music, WERO plays a key creative role in shaping the visual identity of FOURSIDE Records and is responsible for much of the label’s design. In addition, he connects music and fashion through collaborations with the Zurich-based fashion label D’Constructed, where he has designed his own fashion collabs and acts as an ambassador. WERO is not just a DJ — he is an experience.
