Kim Kwang-seok was a South Korean rock star who died in 1996. 25 years later, his fans could hear him sing again. He sang a song which did not exist when Kim was alive.
How did it happen? There was a TV show, and the producers planned to bring Kim back to life. An AI company used a special program which recorded Kim´s songs. The AI then learned to show feelings and emotions in songs. The program learned 20 of Kim´s songs, and the AI sang 700 Korean songs with Kim´s voice. After this training, the AI could sing a song which Kim could not know because he died before a songwriter wrote it.
Some people were happy when they heard Kim again. The producers were not sure if they did the right thing. They had to speak to Kim´s family, too. Kim´s family was very happy with the new song.
