What a scrumptious spread of musical virtuosity the Barbican has laid on with the aid of its international guests this week.

Presenting the last Mozart symphonies as a three-act opera for orchestra, as Richard Tognetti and his febrile fellow Australians did on Monday, was always going to be a supreme challenge. It worked, as Boyd Tonkin reported here. Since then, the Barbican's grandiosely-named "International Associate Ensemble" has opened up the repertoire, synchronising with film (on Tuesday) and ending its mini-residency with the kind of vibrant rattlebag for which it's rightly celebrated.

Here it comes - get a grip. The tears have started flowing in the trio "Quid sum miser" and 12 minutes later, as the tenor embarks on his "Ingemisco" solo, you have to stop the shakes turning into noisy sobbing. The composer then lets you off the hook for a bit, but only transcendent beauty in singing and playing can achieve quite this effect in Verdi's Requiem.

Joseph Phibbs is not the first composer to make an opera out of Strindberg’s Miss Julie, and it is not difficult to see the operatic appeal of this taut, passionate three-handed drama.

Supernatural wonders, consciously avoided in Rossini's enlightened tale of goodness rewarded La Cenerentola and unrealised by second-rank composer Isouard in his 1810 Cendrillon, recently uneathed by Bampton Classical Opera, flood Massenet's gem-studded version of the Cinderella story. For a contemporary production to avoid visual representation to match would be foolhardly; but to yoke magic to an alternative narrative can also be confusing.

After exhausting years of financial and artistic crisis-management at the Coliseum, English National Opera urgently needed an ironclad, feelgood success. This season’s opener, a somewhat idiosyncratic take on Strauss’s Salome, was unlikely to fit that bill.

There was no synopsis in the programme for the Royal Opera’s concert performance of Handel’s Solomon. Maybe that was an oversight, but perhaps it’s simply because there really is no plot to summarise.

Latvia is fighting fit. The recent elections did not see the expected victory for the pro-Kremlin Harmony party; support for the European Union and NATO will be well represented. Last week the feisty Lavtian Ambassador to the UK, Baiba Braže, landed a perfectly diplomatic punch on the smug mug of our latest apology for a Foreign Secretary, taking former Remainer Hunt to task for his outrageous parallels between the EU and the Soviet gulag by reminding him how Latvia had suffered under the USSR and how eagerly it has adopted the best European values.

Baroque repertoire doesn’t seem to register on most British opera company’s schedules these days, so it is good to see ETO devoting their autumn season to Handel, Purcell and Bach, with some additions from Carissimi and Gesualdo for good measure. Their first production, Handel’s Radamisto, is a good choice for touring, a compact six-hander with strong characters and great music.

Two days after announcing his appointment as their next chief conductor (he takes the reins officially next summer, in time for the Proms), by remarkable good fortune the Manchester-based BBC Philharmonic was able to present Omer Meir Wellber as the conductor of their second Bridgewater Hall series concert.
