This is Impromptu Op. 31 by Vladimir Valjarevic. It is my favorite performed.
As I had mentioned above, I didn't spend sufficient time with this impromptu to get it fully up to tempo (allegro molto), so my play time was about 4.5 minutes--too long. The recording I have of this piece at home is by Vlado Perlemuter (on Nimbus), very nicely done despite his advanced age at the time of the recording in the early 1980s. His rendition goes for 4 minutes. The Valjarevic recording is fairly close to 3.5 minutes in duration. And I agree, it's certainly a fine recording with a lot of flair. My theory on the tempo is that allegro molto must be quick and animated. Like any Italian tempo marking, interpretations can be subjective though. (Look at how fast Toscannini played some of Beethoven's symphonies!!) Yet if Faure meant the tempo to be presto or prestissimo, he would certainly have indicated that instead--which he did not do. So that leaves us with general performance practices--which vary, citing Perlemuter and Valjarevic as two examples at hand. The form of this piece is A-B-A-B. The tempo marking certainly applies to the A sections. As for the B sections, Faure gave no separate tempo marking of his own for those sections, but nearly all pianistists intuitively relax the tempo there in order to bring out Faure's wonderful lyricism. I think the danger is that if the A sections are played too fast, they take on a mechanistic character. Then because the B sections must be somewhat relative to the tempo in A, it can cause the B sections to be a bit more rushed than they ought to be as well. So there is a fine balance there. My sense is that Valjarevic does push the envelope on the tempos. I don't believel I'd want to play the piece that fast, but it's just my personal view on the matter.
