This is a truly fascinating CD. Perhaps it doesn't have the greatest balance in terms of pieces, but that certainly shouldn't put you off at all.
The opening piece (the title track if you want to be "pop") is a truly sublime Lisztian work - you'll find none of the fire and virtuosity that you may have come to expect from him. Seems rather ironic, that a piece written by one of the most "aggressive" composers for another one of the most "aggressive" composers is really quite sublime - no Wagner tubas either.
However, that piece provides about 1/15 of the music presented on this album. The other two pieces, by Berg and Webern respectively, are very good ways to "get into" these two composers. We like to associated them with dry, cold, inaccessible serialism, an exceptionally unfair label on both the composers and the style. We, of course, forget that Berg actually had a very post-Romantic sound to his music (he found the "right" set of 12-tones, perhaps?). These pieces, however, are truly quite accessible, while still providing a fair representation about what these composers are all about. Personally, I prefer the Webern - I'm quite drawn to how he compresses everything into the bare essentials, and yet maintains every ounce of expressivity.
Naturally, Kronos Quartet plays these pieces brilliantly. And equally naturally, the recording quality is top notch. This is definitely worth a ... investment.
