This article examines the challenges of sustainability faced by community archives and museums that are concerned with the preservation and display of the material culture of popular music’s recent past. The sustainability of grassroots sites of popular music heritage is of great concern due to their role in making accessible cultural artefacts that have limited representation in the collections of more prestigious institutions. Drawing on three sites that have ceased operation – Jazz Museum Bix Eiben Hamburg, Mutant Sounds and Holy Warbles – the article highlights difficulties faced by the founders and volunteers of physical and online archives in sustaining their ‘do-it-yourself’ heritage practices in the medium- to long-term.
