On Friday nights "Riverwalk Jazz" tells the story of jazz in America, ranging from turn-of-the-century blues and cakewalks, to swing of the 1920s and '30s. Hosted by the storyteller David Holt and bandleader Jim Cullum, "Riverwalk Jazz" features the Jim Cullum Jazz Band and special guest artists. The program was heard on the NPR News and Classical Music Network Fridays at 9 p.m.
