Spending his childhood in the countryside, he grew to love the sounds of "Nongak", a traditional Korean music form associated with farm life.

He made his debut at the age of 46, at which time he was working as an electronics salesman.

Shortly after choosing music as his full-time vocation, Jang released his first album, entitled "HareulganeungilPassage to Heaven"), featuring pianist
Im Dong-Chang.
This album reflected the values and lifestyles of the poor Korean population living in the small villages and towns of Korea.
During this time, Western pop music was extremely popular in Korea, but Jang's debut album made a huge impact on mainstream Korean music.
He began to garner a reputation as a unique and powerful singer.
Jang went on to win the Jeonju Daesaseub (a traditional Korean music contest in Jeonju City) in 1994, the same year that his debut album was released.

Jang believes that music is an international language, and that without using words at all, he can communicate through song.
Jang Sa Ik's music is often a combination of his own compositions and traditional Korean poetry.
He often incorporates "kukak", traditional Korean folk songs in his music.
His music has been described as "hot and spicy, like garlic".
