There's not much Yoo Hee-yeol can't do. As a celebrated radio DJ, TV show host, record label owner, illustrator and composer, he still finds time to shine as the sole musician behind Toy. A shape-shifting project, Toy's music can vary from heart-wrenching piano ballads to uplifting, guitar-driven K-pop and often includes guest vocalists like E Z Hyoung, giving each song a unique, carefully-crafted identity. Hee-yeol's work outside Toy is just as eclectic—whether it's simple, delicate piano compositions or bouncy ambient electronics, his varied background imbues the songs with finesse.
