Koji Kondo
Koji Kondo is a Japanese video game composer and sound director who is employed at Nintendo. He is best known for his involvement in numerous titles in the Mario and The Legend of Zelda series of video games, among other games produced by Nintendo.
Kondo was born in Nagoya, Japan, on August 13, 1961. He began taking lessons in the electronic organ from the age of five. He improved his skills in the instrument in a cover band that played jazz and rock music. Kondo studied at the Art Planning Department of Osaka University of Arts, but was never classically trained or particularly dedicated to music. However, he gained some experience in composing and arranging pieces, using both the piano and a computer to assist him. During his senior year, Nintendo sent a recruitment message to his university stating that they were interested in hiring people dedicated to composition and sound programming. An LCD and arcade gamer, Kondo successfully applied for the job in 1984 without requiring any demo tapes.
