One of the greatest baritone arias ever is O du mein holder Abendstern from Tannhauser.
Like a premonition of death, darkness covers the land,
and envelops the valley in its sombre shroud;
the soul that longs for the highest grounds,
is fearful of the darkness before it takes flight.
There you are, oh loveliest star,
your soft light you send into the distance;
your beam pierces the gloomy shroud
and you show the way out of the valley.
Oh, my gracious evening star,
I always greet you like happily:
with my heart that she never betrayed
take to her as she drifts past you,
when she soars from this earthly vale,
to transform into blessed angel!
I’ve seen Håkan Hagegård at the Met, in their magical production of Tannhauser, several times.
