K4OS

K4OS is an Argentine girl group composed of Mariana Taurozzi, Inés Civit, Mercedes Bitzer, and Lynette Ladelfa, bringing a fresh take on Argentine pop with strong influences from K-pop. The group was formed in 2023 when Taurozzi gathered the members to create a girl band, and their first songwriting camp led to the development of their initial tracks. They built a strong fanbase by documenting their training process through reality-style videos and mini sketches on social media, engaging thousands of followers. K4OS made their official debut on February 7 with the single "Caos," followed by "Extra" on May 14. In July, they released "Mente en Blanco," along with its official music video, solidifying their presence in the Latin pop scene. 2025 saw the release of the dance pop track "Ufff Baby."
