You can always be sure of impeccable casting and spirited playing as Ian Page takes his Classical Opera through Mozart year by year. Just don't expect more than the glimmer of genius to come in 1768, though. It doesn't matter in those admirable showcase programmes highlighting the young Amadeus alongside more mature voices of the year in question.

Singing satirist Anna Russell placed the French chanson in her category of songs for singers "with no voice but tremendous artistry". Mezzo Karen Cargill has tremendous artistry but also a very great voice indeed, a mysterious gift which makes her one in a thousand, and also rather good French (put that down to Scotland's "Auld Alliance, perhaps).

With the eyes of musical fashion turned relentlessly on the calculating stage works of chilly alchemist George Benjamin, hopes ran high for a brighter spark in a new opera by his contemporary Mark-Anthony Turnage.

Violins, violas, wind and brass all standing for Schumann: gimmick or gain? As John Eliot Gardiner told the audience with his usual eloquence while chairs were being brought on for the Berlioz in the first half of last night's concert, Mendelssohn set the trend as conductor with Leipzig's Gewandhausorchester - though as I understand it, only the violins stood - and some chamber orchestras of comparable size have adopted the practice.

Even for a singer as driven, communicative and self-reliant as Joyce DiDonato, the song recital with string quartet is a bold step. Whereas an endless repertoire of songs with piano exists, there is virtually nothing off-the-peg for singer and string quartet; it is a case of commissioning the arrangements, and to some extent building your own art form.

As a scan through the 17-year list of Rosenblatt Recitals quickly reveals, sopranos and tenors come and (often as not) go. Much rarer is the opportunity to enjoy the gifts of a mezzo-soprano near the start of what should, all things being equal, be a long and illustrious career.

Wherever you are in the world, opportunities to see Cecilia Bartoli perform are hard to come by. A one-off chance to see her sing Mozart in Rome was not to be missed. This was a rare homecoming for Bartoli. Born in Rome, she studied at the city’s Conservatorio di Santa Cecilia where many members of the orchestra teach.

To catch the searing desolation of a lover scorned, you need to be the complete artist, with temperament and technique in perfect equilibrium. Mezzo Christine Rice has taken us from Berlioz's Marguerite and Mozart's Donna Elvira at English National Opera via Birtwistle's Ariadne to Haydn's, and - most taxing of all - the end of an affair by telephone in Poulenc's La Voix Humaine.

Most singers give recitals, and very nice they are too. But there are some – Bartoli, Florez, Netrebko, Terfel – who really put on a show. Mezzo Joyce DiDonato might just be the queen of this select band, and between the projections, smoke, sound effects, costume changes, lighting design and a solo dancer, her latest project throws down the gauntlet to any singer who thinks it’s enough just to learn the music and turn up in a clean frock.

What's a world-renowned mezzo-soprano in her middle years to do? Slimline of voice, tall and handsome in person with piercing and slightly intimidating blue eyes, Stockholm-born Anne Sofie von Otter isn't likely to sing what is known in the operatic world as "all those old bag parts", though she's a good enough actress to have carried off a few.
