Justus returns with “Flashback,” a high-energy festival anthem born from a spontaneous late-night studio session. What started as a playful jam with some classic EDM-style leads quickly turned into something serious. The track channels the pure energy of those unforgettable moments in the crowd — inspired directly by Justus’ own memories of watching Martin Garrix perform. Flashback is built for the mainstage and ready to make its mark this festival season.
