A muse of fire descended on the top floor of a former warehouse in the East End, unextinguished by the rain which fell almost continuously outside during the four stupendous concerts – three advertised, one a generous bonus – of the Ragged Music Festival.

This concert by Sir Bryn Terfel and the Britten Sinfonia, the very first concert given at the Barbican in front of an audience since 15 March, was surely in need of some stronger explanation than that offered by the blurb for the evening, namely “comfort and familiarity” and a “remedial tonic of an evening.”

Salzburg, Verbier and other high-end festivals have scraped together reduced, still impressive programmes over the summer for consumption online. Not so starrily cast but hardly less engaging in situ is the adapted offering from Istanbul, mixing local and international artists, chamber and orchestral concerts with a flair that belies its reputation on the fringe of the major music festivals.

Like many musicians, Danny Driver had not given a recital since the pandemic took hold in March. His return to the platform took place in the intense spotlight of the Wigmore Hall, broadcast live in BBC Radio 3’s Lunchtime Concert and webcast to the world - for which he chose a programme that was demanding, exposed and imaginative and rose to its ferocious challenges as if butter wouldn’t melt. 

There should eventually be a plaque on the outside of the Fidelio Orchestra Café in Farringdon, to the effect that London’s musical life after lockdown re-ignited here. And how, in early July, with Steven Isserlis exuberantly stepping up to play Bach before a rapt small audience.

How do they do it? Bach and Angela Hewitt, I mean, transfixing and focusing the audience in the Wigmore Hall – at home, too, hopefully, thanks to the livestreaming– through 13 and three-quarter fugues and four canons, all starting in the same key and (until the last) on the same theme, plus a benediction, the glorious whole amounting to an hour and a half without a break.

Clearly it takes peculiar circumstances for some of us to hear the Academy of St Martin in the Fields within its eponymous church – that’s a first for me. The lure was considerable. Quite apart from the relative dearth of live events in London, the programme was of the imaginative kind more ensembles should be thinking about: three solos by a German, a Frenchman and a Scot resonating between each other, followed by the addition of increasingly larger groups of players, a kind of paradigm for lockdown and thereafter.

Songs of the beyond versus the profundity of the here and now struck very different depths in the Castalians’ evening concert at the Wigmore Hall and Elizabeth Llewellyn’s recital with equal partner Simon Lepper the following lunchtime. It was good to have the very human anchoring of Haydn’s “Emperor” Quartet, Op. 76 No.

There was a rainbow over the Royal Festival Hall as I crossed one of the Hungerford foot bridges for the first time in six months. The lights and noises inside did not betray the augury. Was it the sheer hallucinatory pleasure of being within the auditorium with a handful of other spectators watching and hearing a full orchestra after what felt like a lifetime?

My first time back in a concert hall since March was also, more significantly, the first time back for last night’s Wigmore Hall performers, guitarist Miloš Karadaglić and saxophonist Jess Gillam.
