I ordered this CD set based on the samples, and expected to most enjoy the Pierne concerto. However, I found the Pierne, and most of the material here, fairly uninspired. The real highlight turned out to be the piano concerto by Edouard Lalo.
Lalo is best known for his Symphonie Espagnole violin concerto. I have subsequently also heard his cello concerto, his symphony, and miscellaneous orchestral pieces. They all struck me as competent but ultimately unmemorable. Not, however, this piano concerto. I think of it as an "old man's concerto" - there is a sense of experience and perspective, even nostalgia, while the structure and melody are individual without apology, and without self-consciousness. It is cyclical in form, i.e. there is a central theme that recurs in all movements, and the influence of Saint-Saen's concertos predominates, particularly in the translucent orchestration, but also in elegance of melody and feeling. Perhaps inspiration is a little diffuse in the final movement. Nonetheless, this concerto rightly belongs in the repertoire, and I hope that some musician of prominence will decide to champion it in the concert hall and on record.
There is only one other recording of this concerto available (David Gross with the Staatsorchester Frankfurt (Oder), and Nikos Athinaos conducting, on Signum). It is quite good, and has the advantage of better sound than these old Vox recordings, but I find the soloist overly mannered and too delicate. Marylene Dosse here plays with sensitivity and skill, but also with strength and vigour, matched by the Stuttgart orchestra under Kuntzsch, and the performance sounds convincingly grand. You can alleviate the poor sound somewhat by tweaking the EQ (in particular, turn down the treble). Until more alternatives are available, this is the recording to own, and if you love piano concertos then own it you should!
