In April 2019, the brass ensemble phil Blech Wien, under the baton of Anton Mittermayr, joined forces with Olivier Latry to present an extraordinary programme chosen with the aim of bring the tradition of Viennese sound to a wider appreciation, not through the usual juxtaposition, but through the merging of two sound worlds—realized through the unique arrangements of Mark Gaal. After a hugely successful first performance in the sold-out Kulturpalast Dresden with its new Eule organ, the concert was repeated and recorded a week later in the Great Hall of the Musikverein in Vienna: Olivier Latry on the 6,138-pipe, 81-stop Rieger organ—which he had inaugurated eight years before—and the 17 other musicians create an atmosphere, beauty and power of sound normally associated with large orchestras.
