Kirsten joins Kathryn to look at skiffle, a type of "folk music" performed with a mixture of manufactured and handmade instruments.
Originating in the United States in the first half of the 20th century, it became popular in UK in the 1950s.
Skiffle was a major part of the early careers of some musicians who later became prominent rock performers, such as the Beatles.
Kirsten Zemke is an ethnomusicologist at the University of Auckland's School of Social Sciences.
