South Korean band Can't Be Blue officially debuted in June 2024. The group's name reflects the members' musical philosophy, aiming to convey messages of not being trapped by melancholy and bravely pursuing happiness through their work. Their music, characterized by refreshing and bright guitar lines, intricate melodies, and emotionally rich lyrics, often explores themes of encounters, partings, and complex emotions in love, gradually gaining recognition within the Korean band scene.

Their debut single, "Within the Words Once Called Love (사랑이라 했던 말 속에서)," garnered attention upon its release, with its music video surpassing one million views on YouTube. Lead vocalist Lee Do-hoon's distinctive vibrato and the rich, layered arrangement have become Can't Be Blue's most recognizable musical traits. As their work continues to gain popularity, Can't Be Blue also secured the top spot as Spotify's "K-Pop ON!" Best Streaming Rookie of 2025, showcasing the formidable musical potential of this new generation of Korean bands.

Can't Be Blue recently made history at a world-class band competition held in Germany, becoming the first Korean band to win the championship. Following the news of their victory, the lead vocalist's family background unexpectedly came to light: his father is none other than the renowned singer Lee Sang-woo (이상우), once hailed as the "Ballad Emperor."

Without relying on his father's fame, the young vocalist first proved his talent on the international stage and received recognition. Now, the story of the father and son has been revealed through a recently aired program, sparking unexpected discussion.

The subject of the buzz is Lee Do-hoon (이도훈), the lead vocalist of the five-member band Can't Be Blue, whose group's works have accumulated over 26 million views on YouTube. His father is singer Lee Sang-woo, famous for his hit song "100 Meters Before Meeting Her" (그녀를 만나는 곳 100m 전).

Lee Sang-woo recently confirmed his son's identity during a recording of the KBS program "Hwang Shin-hye's Let's Live Together." He revealed that he personally taught Lee Do-hoon music from the age of four. He also shared that he and his family have long supported his eldest son, who has a developmental disability, a journey that has strengthened their family bond.

Lee Do-hoon's band, Can't Be Blue, has already proven its capabilities on the international stage. The band recently traveled to Rothenburg, Germany, to participate in the "Emergenza Festival," one of the world's largest competitions for emerging bands, where they ultimately advanced through the rounds to claim the overall championship.

This marks the first time a Korean band has won the Emergenza Festival since its inception in 1992. Can't Be Blue ultimately scored 267 points from the judges, defeating strong contenders from Japan, Italy, Denmark, and other countries, successfully setting a new record for Korean bands in the competition.

The Emergenza Festival is considered an important platform for emerging bands, with over 300,000 musicians having participated to date. This victory not only brought international attention to Can't Be Blue but also brought pride to the Korean independent band scene, successfully showcasing the strength of Korean bands abroad.

In addition to being a vocalist, Lee Do-hoon is also a composer, demonstrating his multifaceted musical talent. Can't Be Blue officially debuted in 2024 with "Within the Words Once Called Love (사랑이라 했던 말 속에서)," a pop-rock track featuring bright melodies paired with poignant lyrics, gradually building their fanbase.

After the news broke, many netizens left comments cheering on Lee Do-hoon, saying, "Indeed, talent runs in the family," and "I hope he doesn't just rely on his father's fame but makes his own mark with his unique charm."

Lee Sang-woo debuted in 1988 after winning the Grand Prize at the "Gangbyeon Song Festival." He later released numerous hit songs, including "Sad Love Like a Painting" and "A Dream of One Night," securing his place in the 90s music scene. Now, his son Lee Do-hoon is taking up the mantle, standing on the international stage with his own musical prowess, as both father and son forge distinct yet equally brilliant musical paths.
