Michael Halasz's Schubert Symphony 4 has been called stiff by some, but I recommend it. If Halasz isn't over the top with emotion, nuances and ritards at cadences, he is not insensitive and conducts Schubert's Symphony 4 with the Failoni Orchestra very sensibly. All the tempos are correct, and III, the Minuet, does not turn into a blur at a lightning speed, as do some recordings of this movement.
The "Grand Duo" Symphony in C is another reason to consider this disc, as it is equally well played, and recordings of the "Grand Duo" are hardly thick on the ground. Again, the Failoni play very well at Halasz's speeds. The "Grand Duo", however, is not really from Schubert's "top drawer" but is quite good; there is some repeated thematic material some listeners may find dull, but the orchestral version of this 2 piano work does work most of the time. I've heard alot worse with transcriptions, and enjoyed it alot.
The only other "Grand Duo" recording by an orchestra I know of is the Abbado/Chamber Orchestra of Europe (DG), which may be hard to find. I have not heard Abbado's "Grand Duo", so cannot recommend it. For Schubert 4, there is the excellent Ormandy/Phialdelphia (Sony "Essential Classics"), Bohm/Berlin (DG, in a set of 8 Schubert Symphonies), Baremboim/Berlin (CBS), and Kubelik/Vienna (EMI, on a Seraphim 2 disc reissue with Barbirolli's Schubert Ninth, but may be hard to find now.)
Given this information, I recommend Halasz, for price,
excellent sound, and playing by the Failoni Orchestra.
