No! Where can I get hold of the CD(s)?
The website HGZ (http://www.hgz.hr/) (Croatian Music Institute) mentions them (there's at least 2 CDs offered of which the one mentioned is one...) and I assume that the institute creates and sells them, though I see no ordering information just offhand. One relevant page may be http://www.hgz.hr/index.php?option=com_content&view=article&id=67&Itemid=79 (http://www.hgz.hr/index.php?option=com_content&view=article&id=67&Itemid=79).
