Music developed relentlessly in the tense environment of the 19th century. Many composers broke away from firmly established conventions, taking ever greater liberties and forming a counterpart to the industrial and technical revolutions taking place at the same time. Singer Pur traces that arc of tension in this programme, in which the individual composers no doubt differed widely in their attitudes to faith and spirituality. Anton Bruckner, known for his almost childishly blind faith, probably struggled far less with his attitude towards God than composers such as Franz Liszt or Max Reger.
