"Whether lashing out in fortissimo melismas or whispering in pure-tone pianissimo, Boesch probes totalising extremes. Other principals match Boesch's top quality, particularly Arditti, whose climaxes command a lithe, powerful core, but whose central aria, 'Oh Lord, whose mercies numberless', is arrestingly still. Guth's [staging] sometimes works against both the libretto and the music ... Mancini's [video] efforts, by contrast, help restore 'Saul's' dramatic coherence".
