Rachmaninoff’s 4th Piano Concerto didn’t deserve to be cut. It seems to have received, in any version, the homeric epithet “Rachmaninoff’s least popular” since it wasn’t popular at the première (1927) and wasn’t much more loved after the revisions (1928 and 1941), but this is perhaps as much due to the immense and perennial popularity of the 2nd and 3rd as any intrinsic quality of the 4th, and the unpopular label seems now to be beginning to give the original version a little bit of underdog cred. The original longer version was only published in 2000, and this performance, according to the Sydney Symphony, is the first of this version in Australia. It is a fascinating case of audience expectations based on a composer’s perceived style and the composer worrying too much about pleasing them. Luckily the original was not lost. Even so it is not very long, though it does have a leisurely, operatic quality to its pacing, almost a Mahlerian pace, but with its drama turned in, more psychological and untidy than the other concerti, and so it is not as exciting as the other concerti. It does not have too solid a form holding it together, it doesn’t tell a ‘story’ with beginning middle and end as the others do more obviously. It is not linear, or at least it is taller than it is long with all those enormous, thick, rich chords which defy a simple analysis and the long runs of impossibly fast notes which are not exactly melodic — maybe more harmonic as they ring in that resonant Steinway piano — but the melodies in the piece with the exception of the opening one are more like fragments of leitmotif without staging to help explain them. The opening theme returns here and there but it seems odd in its return, almost an interruption of the of the pensive, contemplative revery of the music, almost like the sudden landing of an eagle, or an angel, or a strange golden shaft of light. But the 20th century romantic music doesn’t need a strict form since Rachmaninoff’s concept is not architectural or plastic. The wonderful thing about music is that you don’t have to worry whether it will stand up.
