For more than six decades, Adrian Boult was at the forefront of British music-making. He was the most skilled British conductor of his era, with the widest musical sympathies. Known for his conducting style characterized by it's clarity, discipline, and objectivity, his recordings are highly regarded for their integrity and musical insight. This edition includes all his mono recordings made between 1920 and 1957 for HMV, Pye Nixa and Parlophone labels. More than half of this box set is available for the very first time on CD, in HD remastering made from the original sources, and it includes several previously unreleased recordings. This first box devoted to the Mono recordings will be followed in January 2026 by another box devoted to the complete Stereo recordings by Adrian Boult on Warner Classics. The albums are presented as original pairing programs with original cover artwork.
