Sir Simon Rattle conducts two composers as united in their devotion to the Catholic as they are divergent in their approaches to writing music; Bruckner’s Eighth Symphony a fiery dramatic opus, while Messiaen’s Couleurs de la Cité Céleste is meditative and sparse. Revered French pianist Pierre-Laurent Aimard joins a reduced Orchestra in the 20th-century work, offering an expert rendition of Messiaen’s often overlooked work.
