This is a wonderfully inexpensive, introduction to the music of Myaskovsky, an underrated composer whose complete symphonies are only now appearing on CD (largely thanks to Olympia).
Both these works are entirely characteristic of the composer, with typically soulful and uplifting themes.
Svetlanov's recording of this coupling was once available on a long deleted Melodiya CD and the 25th is available, coupled with the First symphony on Olympia in a marvellous performance. However, I think that the war-time 24th Symphony is a more interesting work than the First symphony and Yablonsky's performances are also excellent. Furthermore, the new Naxos disc is a more recent recording.
The 25th Symphony has one of Myaskovsky's most moving, typically Russian tunes (about five minutes into the opening movement)and both conductors bring out the poignant lyricism of Miaskovsky's score. On balance, however, I prefer Svetlanov's slower rendition on Olympia (Yablonsky is about five minutes faster in the opening movement)
So, I think that Svetlanov's Olympia version brings out the tragic grandeur of the epic 25th Symphony even more successfully than does Yablonsky but Yablonsky's is also a fine performance with a more interesting coupling. As the Naxos disc is so inexpensive you could buy both versions! Highly recommended to Myaskovsky fans and as a wonderful introduction to his music.
