I've just seen a nicely produced collection of Transylvanian Hungarian ballads and lyrical songs, collected up to last year from singers ranging from age 81 to age 15: Lajos & Matild Kristály, Domokosi nagy hegy alatt: Csíkszentdomokosénekes népzenéje 1948-2008, ISBN 978-973-0-06612-8, 2009. It's in the local bookshops but has no publisher indicated (presumably published by the collectors). Nicely done with colour photos of the regions and the source singers. Csíkszentdomokos (Sandominic in Romanian) is a small town in eastern Transylvania.

I get the impression that sort of thing is not considered surprising round here.
