The origins of OKOS were laid when Özer Öcek (Guitar) and Anıl Yüksel (Vocals) started composing their own songs as an anonymous duo during their university years. After university life, the duo continued to work at home, and with the joining of Sidar Gökçe (Drums) and Metin Emre Yelis (Bass Guitar), the band took on its identity. With the joining of Tan Ata (Guitar) to the group, which adds new ones to its repertoire of compositions day by day, OKOS took its current form.
The band, which aims to offer different flavors to listeners with its rich and dynamic style by taking advantage of the wide range of rock music, released its first single "Başına Gelecek Var" on March 1, 2024.
