Three things combine to make this a worthwhile recording. First there is the sound. The sound in RCA's Living Stereo series of recordings is superb. I have a few and intend to purchase more.
The second is the orchestra, the Chicago Symphony Orchestra. Fritz Reiner was noted as an accomplished orchestra-builder and the Chicago Symphony is regarded as his greatest achievement. Igor Stravinsky is said to have described it as the most accurate and flexible orchestra in the world. It plays here with refinement, beauty and power.
The third element is the conductor. Fritz Reiner was born in Hungary but his greatest achievements were in America. He was not a showman on the podium. He conducted with a minimum of extravagance and show. But he achieved wonderful results, as we find here.
If you buy this recording you will have music that will give you great delight in both symphonies. Is it a great recording? It possibly just misses that accolade. He has some very strong competition in both these symphonies. Listen to Kubelik and Klemperer. Klemperer is more measured in his approach, but there is a tension in it I find missing in Reiner's playing.
Having said that, I recommend this CD wholeheartedly as well worth buying. I think you will enjoy it and return to it often .
