Katya Apekisheva and friends made a persuasive case for Hummel's Piano Quintet to be heard as a transitional grand romantic concerto deserving of belonging in such august company.

With more than a hundred Academy students hanging over their seats at the side of the hall like their equivalents in The Red Shoes 70 years ago, nine of the world's finest musicians took on Schubert in Lisbon.

Given reports that an earlier instalment of this Jerusalem Quartet tour had been disrupted by protesters, it's pleasing to be able to write that there were no such disturbances here. It's a good thing too, because nothing should overshadow the exquisite music-making of this Israeli quartet, joined here by Russian pianist Alexander Melnikov. Melnikov and the quartet blended very well.
