His performance in the role of Edgardo in Lucia di Lammermoor at the Teatro Real Madrid in 2018 won praise for his "voice of gobsmacking beauty, thrillingly secure high notes and delicious timbre", where he also offered a concert with the Orquesta Sinfónica de Madrid and conductor Ivan Lopez-Reynoso in January 2021. He made his debut at the Metropolitan Opera in October 2011 in Il barbiere di Siviglia, singing the role of Count Almaviva.
