These are classic recordings from the early age of stereo in the 1950s, through to modern digital classics. That over-used word 'cornucopia' is usually pulled out to describe box sets like this, but what is on offer is an undeniable abundence of some of the finest Decca recordings of the last fifty years. The sound is of extraordinary quality with analogue recordings often easily mistaken for digital. I'm not clear if these have had a new sound upgrade in reprocessing, but on my relatively standard sound set-up most were, in my view, jaw-dropping. The Monteux disc of Ravel's Daphne and Chloe paired with Elgar's Enigma Variations puts to shame some of the recent versions in audio quality (and performance). Other highlights are the Tchaikovsky string serenade by Marriner (wonderful), Messiaen Turangalila Symphony by Chailly (close but not the equal of the under-rated version by Salonen on Sony), a Sutherland/Pavarotti concert from New York, to name a few of the fifty discs (Lucas has usefully listed the collection on this page). People will have their own likes and dislikes, but if you are relatively new to classical music and hungry enough to explore the enormous creative scope that the classical imagination embraces,this is one of the best 'starter packs' of all time; but equally mouth-watering for more seasoned music fanatics who are offered the pinnacle of performance and sound. Beautifully conceived and presented collection, there is no rival to this in the current catalogue. Go for it now and experience unbridled pleasure.
