Lee Changsub

Lee Changsub (이창섭; born February 26, 1991) is a South Korean singer, musical actor, and entrepreneur. He debuted as the lead vocalist of BTOB under Cube Entertainment in March 2012, and has since established himself as one of K-pop's most versatile artists across idol work, musicals, and solo releases. In 2023, he signed with Fantagio and founded the Chang-Ggo Training Centre vocal academy in Suwon. Born in Suwon, Gyeonggi-do, Changsub studied Practical Music at Howon University alongside BTOB groupmate Im Hyunsik. Before his idol debut, he won a Daesang at the 16th Suwon Music Festival in 2008. His solo career began in 2017 with the digital single "At the End" as part of the BTOB Piece project, followed by his debut mini album Mark in December 2018. Changsub pursued a parallel career in musical theatre from 2017 onwards, taking the lead in productions including Boys Over Flowers as Goo Jun-pyo, Napoleon, Edgar Allan Poe, Dogfight as Eddie Birdlace, and Iron Mask. His first full-length solo album 1991, released in October 2024, arrived alongside his cover of Can's "Heavenly Fate" (February 2024), which became one of the year's defining K-pop OST moments. The track dominated streaming and karaoke charts for months. His 2025 mini album Farewell, Fa-rewell continued his introspective solo direction. Beyond music, Changsub is known for his genuine connection with fans, sharp wit, and commitment to craft. He remains active with BTOB as the group celebrates major milestones.
