A rock museum opened in Budapest on 8 February 2014 in the Radnóti Miklós Colosseum, a new cultural and event centre in the 13th district. The displayed material – posters, photographs and other documents, instruments, equipment, artwork – come from a variety of sources, but mostly private collections, and encompasses the years of state socialism, from the birth of Hungarian rock and roll in the early sixties until the 1989/1990 regime change and even beyond. The event posters were often saved by promoters, who have now donated them to the museum; the instruments, equipment, as well as a few stage costume items come mainly from the musicians themselves. The collection is continuously expanding – the curators are aiming at collecting more material from musicians outside Budapest, as at the moment the display primarily focuses on Budapest and shows less of music making outside the capital. The exhibition also features an interactive map of Budapest’s rock music venues – mainstream and underground. The curators have also compiled an accompanying book. There is an accompanying Facebook community. It will be interesting to observe how the collection will grow, and whether online participation and discussion regarding our rock music heritage will continue to unfold.
