Giuseppe Verdi Te Deum
Claudio Abbado
Verdi's Te Deum is well-served on YouTube with a recording with Claudio Abbado conducting the Vienna Philharmonic Orchestra, and the Wiener Konzertvereinigung and soprano soloist Cheryl Studer. Note, however, that this video is of all four of the Sacred Pieces, and the Te Deum starts at 25:26.
John Eliot Gardiner
In a completely different direction is John Eliot Gardiner's performance of the Te Deum with the Orchestre Révolutionnaire et Romantique and the Monteverdi Choir. The tempi are brisk — although closer to the tempo indications that Verdi himself preferred. And, there is a verve and trajectory that is mightily convincing here. Choral singing and orchestral playing are superbly polished — probably more so than any other commercial recording available. A very different experience than Ricardo Muti and Claudio Abbado, but definitely worth a listen!
