James H. Mathis, Jr. (born August 1967), known as Jimbo Mathus, is an American singer-songwriter and guitarist, best known for his work with the swing revival band Squirrel Nut Zippers.
He was born in Oxford, Mississippi to Jimmy Mathis and Jeanella (Malvezzi) Mathis. His genealogy is of Scottish and Italian origin. His early life was filled with music, as his father and relatives were skilled instrumentalists and singers. He began joining the family musical circle at an early age and by age eight was proficient at mandolin. By 15, Mathus had been taught the rudiments of guitar, piano and harmony singing. The family's repertoire consisted of hundreds of folk, bluegrass, country blues and pre-recorded songs passed down through the Mathus and Byrd families. His father was an avid outdoorsman, traveler and also raised hunting dogs and horses. Thus, Mathus' early life consisted of hunting and fishing in the Corinth, Mississippi, area.
Mathus was involved in rock and roll in Corinth High School and was recorded first in 1983 at Sam Phillips Memphis Recording Service in Memphis, Tennessee, in a group called The End. He also helped found Johnny Vomit & The Dry Heaves, which was one of the first punk rock/experimental noise bands in the state of Mississippi.
