First a word about Saraste and Sibelius on other labels. The box set of the 1-7 is out of print, but worth looking up used.
Saraste recorded those for Finlandia records and the individual tracks made it to other labels. The 7th is sold with the 3rd and 6th.
This disc with the 7th is form his RCA recordings in Helsinki in 1989. Similar to Berglund recordings of that period. The recording is fine.
But if you are a Saraste fan, you want to get this Lemminkäinen suite. There is no other recording. The suite runs some 50 minutes, the symphony about 20.
Several other conductors have the Lemminkäinen suite. This is quite good. And the Swan of Tuonela is 2nd where it should be. Fine work by cellist and English horn player.
