RIO (born Kim Ryeong-eun, December 6, 1995) is a South Korean singer-songwriter, producer, and musician whose warm blend of indie, R&B, and soul has defined her artistic identity since she began releasing music in 2017. She first gained attention by sharing covers and original songs on YouTube and SoundCloud before making her official solo debut in 2020 with the digital single “Wash Away.” Over the years, she expanded her discography with singles such as “Dream No.24” (2020), “Fishtank” (2020), “Canna” (2021), “Babe” (2022), “Green Yellow” (2022), and “Milk Choco Quik” (2025), alongside the EPs The Young Lover (2021) and Perennial Green (2022). Skilled in piano and synthesizer, RIO has worked both independently and under Studio Big Blue, continuing to develop her intimate, emotionally resonant sound.
