Hi, welcome on the board!
I think you heard the CD called "Jako santidevi" which Zuzana recorded with her group KOA. She recorded several CDs with a group called Nerez, then recorded 1 CD with a group TRES and finally recorded 4 albums with KOA. You can check Amazon - it offers 2 albums of Zuzana Navarova: Barvy vsecky and Jako Sántideví, you must have both of them
Jako Sántideví was the last one.
