Keilberth 1955 Ring excels by self-effacing conducting

The 1955 Bayreuth Ring conducted by Joseph Keilberth is Ross's favorite precisely because Keilberth had no grand interpretative scheme; he disappears into the music so it comes alive spontaneously, revealing the constant shifting of moods and psychological instability, combined with an incredible cast including Astrid Varnay's Brünnhilde and Hans Hotter's Wotan.
