For a complete Ma Vlast ("My Country") which includes "Die Moldau" try Vaclav Talich and the Czech Philharmonic on Supraphon. The mono sound is quite good, and the performance, incomparable. In stereo, look for the Karel Ancerl (also Supraphon with the Czech Phil.) In addition, George Szell and the Cleveland Orchestra recorded a Moldau with stunning orchestral playing (especially the horns). Coincidentally, all three conductors are of Czech background (Szell was born in Hungary, but his mother was Czechoslovakian).
