I must warn the reader that I write this (and any other) review mainly for my own pleasure, and to (hopefully and to some reasonable extent clearly) convey to any other person my ideas about what I like or don't like about a recording (hoping to gain some sympathy, consequently ;-). I do not have any true musical knowledge whatsoever: I can't read music and I do not have any knowledge about any of the technical aspects of music as such. So necessarily, any and every review I lay down before you is simply the result of what I hear and feel are the characteristics and/or differences between certain recordings, and what I love about them ...
If I may be allowed to draw a comparison between different performances, I would like to compare these recordings with the ones by Howard Shelley (on Chandos). Elsewhere I have described those performances by Howard Shelley as finely crafted, whereby every note is - to my ear - given extra poignancy. The recordings of Rachmaninov's Piano Concerto's by Earl Wild are different. They are more bold performances in the 'romantic' (?) manner maybe, whereby the melodies are played with beautiful legato and are given extra sweep and grandure (helped by the orchestra), with astounding technical bravoura (I can't read music, but this should be obvious even to me?!).
Anyhow, I love these performances, as they are bold, sweeping, full-blooded, with such beautiful (what I would, for lack of a better word, like to call 'singing' or 'soaring') legato. My favorite would be Piano Concerto No. 4. Also, the Rhapsody on a theme of Paganini here receives - to my ears - a wonderfully noble performance, full of technical bravoura (also by the orchestra). (It is certainly one of my favorite pieces for piano and orchestra!)
Nobility of playing is also a defining characteristic everywhere in these recordings, I think, but as a result of this nobility (and maybe exultancy), there may have been a slight loss of lyricism and intimacy in the Second Concerto ... Anyhow, the recorded sound is very full and wide, so that one is able to revel in all of the orchestral and pianistic colors. These are heart-warmingly virtuosic, classic performances that - to the ears of this particular amateur listener - lift this music to a higher plain of excellence, and I - for what it is worth - would like to recommend them to you without reserve.
