"Pedro R. Diaz's English horn solo at the start of the third act was haunting."

Ronald Blum, Associated Press.

"Eloquent as Mr. Álvarez was in the “Flower Song,” to name but one example, his effort was enhanced by the sensitive English horn playing of Pedro R. Díaz. "

"Credit also belongs to the Met's extraordinary orchestra, with extra-high marks to the bass clarinet and English-horn soloists."

"James Levine's orchestra was exceptional, again. And I truly hope he'll consider commissioning a concerto for his remarkable English horn player Pedro M. Díaz, whose contributions in Tristan practically amount to a marquee role, and whose excellence I've noted on several previous occasions."

Steve Smith, The New York Times, TONY Blog, Night After Night Blog.

"But the star of the show was the Met Orchestra under James Levine. The ensemble always plays well, and frequently scales the heights, but the muses were in attendance last night: the playing was uniformly Olympian. Primus inter pares: Pedro R. Diaz in the English horn solos."

"Semyon Bychkov conducted a taut performance, letting the much-heralded Met Orchestra brass rip through the storm scene with gusto. He also summoned beautiful, subtle textures from the band. The English horn solo in Act IV (played by principal Pedro R. Diaz) was as eloquent as any aria."
