A tribute concert has been held annually by singers across musical genres including rock and roll and hip-hop, and his albums sell steadily, marking 5 million copies as of January 2007. On January 6, 2008, the 12th anniversary of his death, a memorial relief sculpture was unveiled at the concert hall where he held thousands of concerts, drawing many fans who memorialized him. In November 2010, more than twenty artists, designers, and sculptors collectively made a mural to the memory of Kim Kwang-seok in the city of Daegu, where he spent his early years. Critics and reporters have analyzed his legacy and the persistent fervor for his music in numerous articles and books such as 'Biography of Kim Kwang-seok, an unsent message' by Lee Yoon-ock and 'The 100 masterpiece albums of Korean Popular Music' by Park Joon-hum et al. From the perspective of history of Korean popular music, he is the direct descendant as well as the successor of Korean topical folk rock, which was initiated by Han Dae-su and flourished with songs of Kim Min-ki, Jung Tae-choon, and arguably Cho Dong-jin in early 1970s under the rule of the dictator Park Chung Hee, who was in power from 1961 to 1979. However, even though Kim Kwang-seok's music was clearly rooted in social issues in his early years of his career, he also empathized with the sorrow and frustration of individuals, which had been downplayed in the struggle for democracy. Around the late 80s and early 90s, with the improvement of democracy in Korean society, the young generations began to turn their attention from collectivism and community to individualism and experiences of their contemporaries. Kim Kwang-seok illustrated the lives of people with loving eyes, but stayed composed and measured. Lee Joo-yup, a music critic, argues that his songs portrayed individuals who are constantly wavering on the border of pessimism and optimism, but sublimated the self-consciousness that never gives up the strain of facing reality. "Standing in the midst of the darkness of night, I can't see even an inch ahead, where I am going, where I am standing, uselessly looking around, drifting over the river of life like a floating weed, I may perish at this unknown river bank, stand up, stand up, give it a try, stand up, stand up, like the sprouts in Spring" (Stand up). In January 2021, using artificial intelligence (AI) Kim's voice was heard 25 years after his death on a program aired by national broadcaster
SBS, named "Competition of the Century: AI vs Human". A promotional clip posted in December had been viewed more than 150,000 times. == Discography ==
