Jack White began playing music professionally in the 1960s with the local Springfield rock group, Randy & The Ramblers. Subsequent local pop-rock involvement over the years eventually led to his decision to pursue a career in music. By 1979, Jack had completed a Bachelor's degree in Music Therapy at Illinois State University, where he was guitarist for The ISU Jazz Band.
As a Music Therapist, Jack began composing therapeutic music, beginning with his 1990 album entitled Evening Summer Pond. A variety of his compositions were chosen for use by Southern Illinois University Affiliated Hospitals and St. John's Center for Mind/Body Medicine.
Jack is a multi-instrumentalist for The Emerald Underground, playing keyboards, guitar and hand percussion.
