Yavuz Selim Ö. (born July 3, 1997), known professionally as Kirmar Productions or just Kirmar, is a german-turkish music producer and artist.
He has been releasing projects on his CZcams channel ,,Kirmar Productions" since early 2017.

In his early years, his mother noticed that he would always hit his head against the seat to the beat of various pieces of music and always be surprisingly precise doing it.
After he suffered from a special type of epilepsy because of a horrible fall damaging a part of his brain during 1st grade and staying in hospital for about 3 months around that time, he began to look at the world and the art of music with completely different eyes.

On 30th of September 2019, he published his free mixtape called "The CV Mixtape". The "CV" in the name stands for "Chaos Variety" which he was called earlier in his career.

The rest is history...
