Mark Rummery is a graduate of the University of Sydney, where he studied classical music. After 1980 his interest changed to early Australian music and he began interviewing musicians in country towns. A resident of Armidale, where for a time he was a teacher, he has for many years been closely associated with Barry McDonald and Chris Sullivan as a member of the Horton River Band. His former wife, Cathy Ovenden, also played in the band for some years.
The Mark and Cathy Rummery Collection was purchased by the Library in 1988.
The collection contains 40 tape recordings of folk music, folklore and reminiscences recorded by Mark and Cathy Rummery in rural New South Wales in 1983–88. The performers and interviewees lived in Broken Hill, Menindee, Narrandera, Wagga Wagga, Young, Boorowa, Crookwell, Binalong, Bingara, Bungendore and Sofala.
The collection is kept together in the Oral History Collection at TRC 2276, 2746. The recordings have been catalogued individually.
