The production, which premiered on March 9, stars Lise Davidsen as Isolde and Michael Spyres as Tristan, with the Met’s music director, Yannick Nézet-Séguin, conducting.
It has been widely hailed as a highlight of the season.
According to the British classical music site Bachtrack, Konieczny delivered a "strong, compelling" performance as Kurwenal, Tristan’s loyal companion.
The website said: "Aside from the power of his bass-baritone, his acting sustained a great interplay with the music, interpreting tension, worry and loyal brotherly love with both his posture and his singing."
A critic for the OperaWire website wrote: "Konieczny is the best Kurwenal I’ve had the opportunity to witness. Whether it be his sardonic and aggressive tones in Act One or the impassioned pleas in the final act as he did his utmost to revive Tristan, his voice sparkled in the theater with tremendous clarity. As he lay dying, he hushed his voice to the softest of sounds, the effect a glorious contrast to his more vocally effusive display prior."
A reviewer for the Vulture entertainment magazine highlighted "Konieczny’s Kurwenal watching over his old friend with a mixture of anger, empathy, and vocal elegance" as one of the production’s standout moments.
Six additional performances of Tristan und Isolde are scheduled for March 17, 21, 25 and 29, and April 2 and 4. The April 4 matinee was added due to high demand.
The March 21 performance will be broadcast live in HD to movie theatres worldwide.
Born in 1972, Konieczny holds degrees in both acting and music. Since making his operatic debut in 1997, he has performed at leading venues worldwide, including the Bayreuth Festival.
He is an honorary member of the Wagner Society in New York. In previous seasons at the Met, he appeared in Wagner’s Der fliegende Holländer and the Ring cycle.
