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. 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.
