Mozart was at the cutting edge of technology in the two graceful works he wrote for glass harmonica, whose spinning crystal bowls are made to sound by gentle touch. It is an instrument almost never heard in modern times, and is played today by one of the world’s finest exponents, Thomas Bloch.

New Zealand-born composer Lyell Cresswell unveils his new ensemble arrangement, a Festival commission, of another Mozart oddity, the masterful F minor Fantasia originally written for a mechanical musical clock.

And contemporary US composer George Crumb conjures similarly magical sounds in the otherworldly whalesong evocations of his theatrical Vox Balaenae.

'beautifully led by Georgiqn soloist Giorgi Gevantzseladze'... absorbingly done with house lights down, masked musicians and some striking music playing'
