Re the 3rd by Stan Ruttenberg: Forgive the lack of proper formatting, pasted from a pdf..
"Anton Nanut, Ljubljana Radio Symphony Orchestra, Max Cencic, soprano
Low-price CD on many cheap labels, e.g., Laserlight, about 1989
First Movement - Somewhat brisk opening tempo. String portamenti are there but very gentle. At 3:05 he
ignores the marking "hurriedly." From then on the performance is good, not exemplary but with some fine
winds and horns, and on occasion some fine accenting. However, the sound is a little congested in the
loud passages. At 13:33 the descending string passage marked "hurriedly" is better than the first time. The
retard at the end is good and so is the "little-by-little accelerando."
Second Movement - The scordatura violin is OK, not quite as prominent as should be. The pizzicati in the
strings are a little weak. At 4:47 the 'blaring" trumpet is pretty good.
Third Movement - The opening is quite restful, but most of the markings for portamento are ignored,
indeed most of the portamenti are taken as slurs rather than slides. The slides in the horns are there but
hardly. The many caesuri are ignored. At RN 4 the cello portamenti are there. One has to assume,
therefore, that Nanut had considered carefully the markings and which ones to take and which to ignore.
At RN 10, allegro subito Nanut is not as manic as Bernstein and lets the music flow quickly but it is not
rushed. At RN 12, the luftpause is just right, held a little more than in the Bernstein, and hit on the head.
Trumpets and timpani are very strong, but horns recessed. Phrasing is very positive and accented,
resulting in one of the most powerful "Opening of the gates" of all recordings. The ending is peaceful and
beautiful.
Fourth Movement - Restful, peaceful opening with discrete cello portamernti. Max Cencic, boy soprano,
has a clear, unwavering voice, and is indisputably the most "childlike" of all the singers who essay this
role. He is in perfect control and manages his leaps well. At RN 3, plötzlich frisch bewegt, Nanut takes a
faster and most sensible tempo. Max is fine in the next stanza and again at RN 9 Nanut takes a sensible
faster tempo. The vegetable garden is not raced through, and Max handles the enunciation very well.
After again a sensible fast section max sings the "Keine Music ..." beautifully, the eleven thousand young
virgins dance prettily, and St. Ursula herself laughs endearingly, with a very good portamento. The
reprise of "keine music is as "gentle and mysterious" as the first time. All in all, this is a gem of a
performance, and makes this set worth searching out, for a paltry few dollars. This is the best way to hear
a fine boy soprano. Such a singer would get lost in the usual large concert hall."
FWIW i find 1,4,5, and 9 on Qobuz.
