I don't even have a 'top five' for this piece.
My archival 'go to' recording of Das Lied is the middle of the three Bruno Walter conducted; it is archival, and the only one I've cared to own, having heard a good number o others:
Bruno Walter, New York Philharmonic, Mildred Miller, Ernst Haefliger ~ on Sony Classics.
It is the performance out of those three, just as in the Goldilocks story, "the middle one is Just Right," and I think it the most the way it is and goes compared to any other I've heard.
With the three Walter recordings, the first is a bit rushed, the last -- yes with Kathleen Ferrier -- is nonetheless too slow, and has this odd quality almost as if he stopped and said, 'listen especially to this bit here, this bit there, and the flow, and momentum, is utterly broken. [I never buy any orchestral vocal work with the voices considered over the quality of the overall performance, ditto choral works with soloists, or opera.]
The sound of that middle performance is just fine, and I find it the most wholly 'there' recording I've yet heard, other later performances by so many others included.
