With roots planted firmly in his Asian heritage, technique and sensitivity honed by his schooling and experience in New York, and with a singular voice propelled by an intense desire for a more complete artistic expression, Jack combines formidable technique with a penchant for gentle, flowing lyricism that makes his music eminently appealing to both musicians and non-musicians alike. Jack’s music always has the combination of jazz, Brazilian, Rhythm & Blues, pop, funk, and Asian influences which leaves a deep emotionally satisfying impact upon the listener.

Born in Seoul, Korea, Jack absorbed the sounds of rock guitar heroes such as Eric Clapton, Jimi Hendrix, and Jeff Beck before discovering the jazzier sounds of Pat Metheny, Larry Coryell, and Miles Davis. At 17, he traveled to the United States to pursue his passion and later enrolled as a computer science major at Columbia University. A stint as a disc jockey at the well-known station WKCR-FM exposed him to an extraordinary breadth of jazz music. Being a student in New York allowed him to experience first hand the living legends of jazz in the city's renowned clubs, and also enabled him to study first-hand with such guitar luminaries as Larry Coryell, Emily Remler, Bill Connors, and John Scofield.
