I have two of his CD's, I will see if there is information inside case jacket for this portion. I believe he may be a native American. The first heard his music, and purchased his CD, while at Canyonlands National Park, Utah, USA it is comprised of Native American Indian Flute music. I think they are called "Sweet Potato Flutes" due to their shape. The second CD is 1700's-1800's American Patriotic Classics, Civil War era has both Yankee and Confederate songs.
These are photos from concerts where Randy Peterson played, so they may be of other bands that played the concert as well.
