Sorry - probably being stupid, as usual; can't see a title for the Boldiszar piece. Someone put me straight, please !
It's just "Prelude, Chorale-Fugue and Postlude for Orchestra". This piece was composed in 1969. The composer's name is Boldizsár Csíky, with s and z reversed in Boldizsár, and it seems that actually, Csíky is his family name. Boldizsár, by the way, is nothing but the equivalent of Balthazar. He is of Hungarian descent and is partly even listed as a Hungarian composer (that's probably also the reason for the confusion regarding his name - in Hungary, the family name is put first as far as I know). The reason is that he was born and lives in Târgu Mureș, where a large part of the population is Hungarian though the city belongs to Romania.
It's the same with Aladár Zoltán as I wrote in this topic a few months ago: here, Zoltán is the family name as well, not Aladár.
