Bilal Goregen is a blind Turkish street musician from Bitlis who performs in Istanbul, singing and playing darbuka while also imitating drums with his voice. He became known worldwide in late 2020 when a vibing cat edit of his Ievan Polkka performance spread across social media. Dilla Dilla comes from that same street performance style, built around a catchy repeated phrase and percussive vocals. The clip keeps circulating because the rhythm is recognisable in seconds and works without context, making it easy to reuse for dances, loops and reaction videos.
