Liszt is one of the most underestimated composers of all time, but I'm sure that anyone who listens carefully to recordings like this can change his mind. The only problem I see in understanding this pieces is that their richness (in all senses) make it necessary to listen to them again in order to understand them more deeply. Yet I can say that the exact same thing is true with Beethoven, Bach, Mahler, and all the other hyper-estimated composers. Looking closer, the problem must be that this pieces are almost never played, so it's difficult to know them before you buy a record like this. I say, don't let yourself go with the general prejudice against the Lisztian inovations : the two recordings by Haitink and the other two by Kurt Masur with the Leipzig Gewandhausorchester are a necessity to every curious listener. Each poem is a masterpiece, and you'll hear the orchestra sound like you have never imagined.
