Here is something to chew on.
The Philips Years is a 20-CD (!) set of recordings from the Philips label, all conducted by Dutch-born Bernard Haitink. He is best known as being principal conductor for the Royal Concertgebouw Orchestra (Netherlands) for 25 years, as well as the London Philharmonic Orchestra and the Chicago Symphony Orchestra. This box set (and the set below) were both released in 2014, as part of his 85th birthday celebration.
His performance of the Debussy
Nocturnes is in this set (same as the SACD I linked earlier in this thread), which was my "gateway drug" to his conducting many years ago when I bought the first-issue Philips CD of that work. I have enjoyed his conducting--the performances seem to have a warmer, more humanistic touch without the bombast or clinical sounds that many newer conductors seem to impart on the orchestras.
I actually do not yet own this set, but am streaming it via Tidal at the moment--Vol. 10 with the Liszt Piano Concerto No. 2.
The other set (which is not yet available on Tidal) is a bit more imposing--the 36 CD (!!)
The Symphony Edition, which includes the complete symphony cycles of Beethoven, Brahms, Bruckner, Mahler, Schumann and Tchaikovsky.
That makes the rather small
The Art of Bernard Haitink 7-CD set look minuscule in comparison.
But given the low prices of all of these sets, it's hard not to recommend them--they can be had for less than $2 per disc. One of the advantages of buying during the last gasp of the CD.
