Quatuor Zaïde at the Konzerthaus. -- In the series “Rising Stars” this marvelous French string quartet performed Shostakovitch (op. 108), Mozart (KV 387) and Bartók (Sz 102) – and two movements of Haydn’s Hob. III/48 and III/44 thrown in as encores. The pieces selected made for a great lesson in how the genre has developed between 1782 and 1960. And the enthusiasm of Charlotte Juillard (violin), Leslie Boulin-Raulet (violin), Sarah Chenaf (viola), and Juliette Salmona (cello) was palpable at every turn.
