I agree with one of the previous reviewers: the Marx concerto is certainly the weaker of the two on this CD. It almost sounds like a combination of the worst aspects of late romanticism (cheesy orchestration, excessively flashy piano part, rambling structure, etc.). Not my cup of tea. The Korngold concerto is much more satisfying (IMHO). True, its narrative structure is not flawless, but it holds together well enough (like Liszt's Sonata in B minor, it's basically one gigantic sonata-allegro movement, encompassing a "slow movement" and a "scherzo" in the development section). It contains some of Korngold's most interesting harmonic progressions (the initial presentation of the opening theme, for example), and the writing for the left hand is very effective (almost as ingenious as that in Ravel's left hand concerto). There is only one other modern recording of the Korngold concerto (on the Chandos label), but the present recording is hands down much better -- it has more thrust and forward momentum, and certain details like inner lines and splashes of colour (like some of Korngold's characteristic harp arpeggios) come across much more clearly. What's more, Hyperion's sound is far superior to the Chandos recording. If you're interested in the rarely recorded and rarely performed Korngold concerto, this is the CD to get.
