Second on the Lakatos family. I have several albums of them that I bought in Prague in the early 90s. My favorite is one with the senior Lakatos with his son. As far as specifically Romanian gypsy music, check out the Hungarian band Muszikas (with their incomparable singer Marta Sebestyen). A couple of their albums are of Transylvanian music, some gypsy, some Jewish. All are available from Amazon. Also at Amazon you can browse through International>Europe>Eastern Europe>Romania. There are some Central European gypsy bands that play more of a Spanish style, sort of like the Gypsy Kings. (One is Vera Bile in the Czech Republic). Good stuff, but very different from Transylvania. A good Czech net-retailer is CDmusic.cz. Search for gypsy or Romany or Tzigane. Good luck.
