Sir Hugh Casson , architect and Professor of Environmental Design at the Royal College of Art, says that his understanding of music has been developed by his personal and professional associations with the theatre and the concert hall - he has designed productions and buildings. His choice of records includes ITZMAK PERLMAN playing a violin concerto by Bach, NETANIA DAVRATH singing one of the Songs of the Auvergne, as well as DUKE EILINGTON playing Mood Indigo and TURNER LAYTON singing Transatlantic Lullaby,
