Until it woke from its slumbers a week or so ago I didn't know this thread existed. I paged back for a while and found some of the comments interesting though I haven't read everything.
The French magazine Classica has a regular feature where available versions of a work are reviewed and a best version decided on. A short list of eight is chosen and three guest critics listen to it blind and rank the recordings in order, with comments. In the February 2017 issue the work under scrutiny was the Symphoninie fantastique so I thought it might be of interest. All three guest critics were French. There is no indication who made the short list. In reverse order recordings were -
No 8 - Jos van Immerseel/Anima aeterna - two of the critics thought it had some interesting points, the third rejected it completely.
No 7. Colin Davis/LSO (1963) - they acknowledged its status as an historic reference of the work but had various reservations.
No 6. John Eliot Gardiner/ORR - they seemed to enjoy it but felt the dry acoustic of the Conservatoire Hall (the original venue) let it down.
No 5. Leonard Bernstein/NYPO - they enjoyed 'la charme et la noblesse' of this performance
No 4. Charles Munch/ Boston SO (1954) - 'une grande reference' - they definitely liked it!
No 3. Pierre Boulez/Cleveland Orchestra - admired for its beauty of sound and the playing of the Clevelanders
No 2. Colin Davis/Concertgebouw Orchestra - sumptuous and virtuosic (the orchestra), elegant (Davis)
No 1. Paul Paray/Detroit Symphony Orchestra - a jewel ('diamant') of the discography. Limitless imagination in the interpretation.
Though it is a fine performance I was a bit surprised Paray was the top choice, I will have to revisit it soon. My all time favourite is still Davis/LSO (1963) though Martinon/ORTF Orchestra runs it close.
