What follows is not a proper review but simply a listing of the contents, which I hope prospective buyers will find helpful. Like the only other "reviewer" of this set, I haven't heard it, at least the whole box, so please take my 5 star rating with a grain of salt. I offer it in part as a corrective to the 1 star rating.
I do have, however - and have repeatedly listened to - a tantalizing single disc of excerpts, 73:10 worth, which includes movements from the 1st, 2nd, 5th, 6th and 7th Symphonies, as well as "Die zwei blausen Augen" from Songs of a Wayfarer and a brief sample of William Malloch's "I Remember Mahler," an audio documentary made for radio broadcast. These excerpts suggest that this box is chockfull of truly amazing performances, and the numerous reviews I've read say as much.
Symphonies 1-9; 2 mvts. from No. 10; Das Lied von der Erde; Songs of a Wayfarer.
