Old K-pop: Lee Deok-jin & Shin Sung-woo — The Heartthrobs Who Made Rock Mainstream in Early 1990s Korea

While dance music was transforming Korean pop in the early 1990s, another trend was unfolding at the same time.

Long before the era of idol fan chants and official fandom names, two rock singers were capturing the hearts of young audiences—especially female fans—with their music, charisma, and unmistakable stage presence.

Those artists were Lee Deok-jin (이덕진) and Shin Sung-woo (신성우).

Today, international fans often remember the early 1990s as the beginning of modern K-pop through dance groups like Seo Taiji and Boys. But during the same period, Lee and Shin proved that rock could be just as commercially successful, helping expand the musical landscape of Korean popular music.


Rock's Two Heartthrobs

Although their musical styles differed slightly, Lee Deok-jin and Shin Sung-woo occupied a similar place in the industry.

Both combined melodic rock with strong vocals, both appealed to mainstream television audiences, and both attracted enormous female fanbases through a combination of music and image.

At a time when long hair and leather jackets symbolized freedom and individuality, the two singers became style icons for a new generation.

Music magazines frequently featured them, and fans often compared their music, fashion, and performances, making them two of the most recognizable male stars of the early 1990s.


Lee Deok-jin: Emotional Rock for the Mainstream

Lee Deok-jin helped introduce melodic rock to a wider audience through emotionally driven songs that balanced powerful vocals with accessible pop sensibilities.

Rather than presenting rock as an underground genre, he demonstrated that it could thrive on television music programs alongside ballads and dance music.

His popularity reflected the growing appetite for rock music that was both expressive and approachable, helping broaden the musical tastes of mainstream audiences.


Shin Sung-woo: Korea's "Terius"

If Lee Deok-jin represented emotional rock, Shin Sung-woo embodied the image of a modern rock star.

Debuting with "Towards Tomorrow (내일을 향해)" in 1992, he quickly became one of the country's biggest celebrities.

His shoulder-length hair, leather jackets, and charismatic stage presence earned him the nickname "Terius," after the handsome manga character from From Eroica with Love. For many young women, he became one of Korea's first true pop heartthrobs.

His success reached another peak with "Prologue (서시)," released in 1994. The song remains one of Korea's best-known rock ballads and is still a favorite in karaoke rooms decades later.


More Than Rivals

Although fans often compared Lee Deok-jin and Shin Sung-woo, the two artists represented a broader movement rather than a true rivalry.

Together, they helped bring rock into Korea's musical mainstream during a period when dance music was rapidly gaining momentum.

Their success demonstrated that audiences wanted variety. While some listeners embraced hip-hop and house music, others found their voice in melodic rock and powerful ballads.

The early 1990s Korean music scene was never dominated by a single genre—it was defined by coexistence and experimentation.


Why They Matter

The story of early K-pop is often told through dance groups alone.

Yet artists like Lee Deok-jin and Shin Sung-woo remind us that rock remained an essential part of Korean popular music during this transformative era.

Their popularity proved that image, musicianship, and emotional songwriting could be just as influential as choreography.

Long before the idol system reshaped the industry, they showed that a rock singer could become one of the country's biggest stars.


Legacy

Today, Lee Deok-jin and Shin Sung-woo are remembered not only for their music but also for defining an era when Korean popular music embraced remarkable diversity.

The early 1990s belonged not only to dancers and rappers but also to rock vocalists, ballad singers, producer collectives, and experimental pop acts.

Their careers serve as a reminder that the foundations of modern K-pop were built by artists from many different musical worlds—not just one.
