시작 (이태원 클라쓰 OST)

The opening guitar riff of "시작" hits like a fist — distorted, urgent, rhythmically precise. Gaho's voice arrives immediately behind it, and from the first syllable it's clear this is a different emotional register than most K-drama OSTs. There's anger underneath the determination, a refusal to accept the verdict the world has already delivered. The production has real rock architecture: layered electric guitars, a drum pattern that drives forward without relenting, dynamics that build toward a chorus that feels genuinely earned rather than manufactured. What distinguishes Gaho's performance here is the control within apparent abandon — he pushes his voice to the edge of roughness without losing precision, channeling righteous fury into something that feels personal rather than theatrical. The song is fundamentally about choosing to begin despite everything stacked against you, about the specific dignity of people who've been written off deciding to write their own story instead. The 이태원 클라쓰 OST needed a track that could soundtrack ambition without irony, and "시작" delivers that completely. It became one of the defining sonic identities of Korean drama's youth-rebellion narrative moment. Play it at the start of something difficult — a new job, a first day, a decision you've been afraid to make. It has the rare quality of genuinely moving you forward.
