Preservation Hall Jazz Band is the name for numerous groups of
Dixieland Jazz and traditional jazz bands at Preservation Hall in New
Orleans, Louisiana, and on tours as organized by the Preservation Hall.
The purpose of the Hall has been to preserve the heritage of both New
Orleans traditional and Dixieland jazz music born in New Orleans and
common to the Riverboats plying the Mississippi River, which spread
throughout the South until the early 20th century.
