What starts as a summer-beach-bar tune with defensive vocals and a warm and relaxed reverbed melodic atmosphere, spreading feelgood vibes as it goes, builds to a sweet surprise. Smooth vocal harmonies erupt in a saturated synth-based groove fireworks all of a sudden, adding flow, texture, and a dance vibe as the tune does its laid-back thing. What makes “sandcastle” so intriguing is the hybrid blend of several style elements. Combining the best of at least two worlds, there’s this unreal drive connected to accessible emotional vocals, making every dancefloor a puddle of molten lava where people move in slow motion while enjoying the unique blend of drive and feeling.
