This is a wonderful box, recommended (almost) without reservation. OK, I did get it for £14.99, but having heard nearly all of it, wouldn't hesitate to buy it at its current lowest price. One or two criticisms to get out of the way first of all:
Yes, the print in the booklet is small, but you get what looks like all the notes from the original discs - 70 pages in English, plus detailed track listing (and of course all the texts on CD 30);
Some of the works included seem to be straining to fit into the 18th century - Beethoven 9, for example, misses by nearly a quarter of a century in time, and several light-years in aesthetic;
The titles of one or two of the discs don't seem to relate too well to their contents: I can't possibly work out why disc 22, "From the Sonata to the Classical Trio" should be made up of three solo harpsichord sonatas by Kuhnau, two (vocal) psalm-settings by Mondonville and two Mozart violin sonatas, beautiful though all these pieces are;
...and then there's René Jacobs's Jupiter symphony, which has garnered equal amounts of adulation and vilification since its appearance. For myself, I found I was just about able to listen to, if not to enjoy, the fiercely hard-driven and humourless Haydn 92 coupled with it, but when the Rossinian crescendos and wild tempo variations of the Mozart started, that's where I turned off. One day I may feel strong enough.
But, these minor reservations apart, there are so many wonderful things here that it's hard to know where to start. For me, perhaps the greatest revelation has been the Haydn sonatas played by Alain Planès, but I could happily listen to nothing but the contents of this box for the next few months and not feel I was missing anything.
