DJ HEARTSTRING is the Berlin-based duo of Leo and Jonas, known for blending euphoric trance, eurodance and high-energy club music with a touch of melancholy. Their sound balances rave intensity with emotional hooks, creating hands-in-the-air moments that feel both nostalgic and fresh. Originally two friends making music for fun, they emerged during the pandemic with their self-described Trance Dance Music (TDM) style. When clubs reopened, their fast-paced, emotionally charged sets quickly found a dedicated audience, driven by unreleased tracks, bold edits and big melodic payoffs. Since then, DJ HEARTSTRING have grown into a global club phenomenon, touring Europe, the US and Asia while racking up millions of streams and viral moments. Whether playing in intimate underground rooms or on major festival stages, the duo’s mission stays simple: big feelings, big energy, and dancefloors that aren’t afraid to feel something.
