Roger Norrington: The Complete Erato Recordings (Erato)

There is no mistaking Christian Gerhaher. His voice is a light, agile baritone, and it is utterly distinctive. He is a very verbal singer, and is as happy delivering his lines in a toneless parlando as he is full voice. But when he does increase the colour, a burnished, slightly nasal tone appears, rich but still light. Emotions are always controlled, and the passion will often build gradually but steadily.

This is the Pavel Haas Quartet’s second visit to a Scottish festival this summer. They were among the stars of the East Neuk Festival at the start of July, and they were every bit as scorching in this Edinburgh International Festival concert.

On a night when any brooks running past the Wigmore Hall might have frozen almost solid, Imogen Cooper’s recital travelled on sparkling waters of the highest purity across almost a century of pianistic innovation.

The screen lights up, the Zoom link connects and there, blinking back at you (30% awkward, 70% enthusiastic) is a familiar face. Is it definitely working? Can you hear me? What do we say now? God, I'm getting old. Even after 12 months of conversation through webcams it still feels forced to me; something to one side of real life, simultaneously weird and routine, intimate and alienating, even as memories of the Old Normal grow increasingly remote. Is that a piano? Well, why not, these days?

Some pianists would take the chance of a birthday celebration to pioneer a solitary epic. Not the ever-collegial, unshowy, some would even say visionary Steven Osborne.

This was the first song recital back at the Wigmore Hall following the second lockdown with a (distanced, 25%) audience. And it was a joy to be back. Great singing. That superb acoustic. A completely rapt audience. And, miraculously, not a single cough.
