It is nearly 50 years since Martha Argerich played in Manchester. She performed with the Hallé Orchestra and the conductor was Claudio Abbado, making his UK debut. That was in 1965 and a year later they repeated their double act. Thanks to the Manchester International Festival and her special working relationship with conductor Gábor Takács-Nagy, music director of the Manchester Camerata, she bridged that gap last night.

As good old Catullus put it, I hate and love, you may ask why. No doubt it's my job as a critic to probe such difficult responses to Britten's Canticles. Why am I so repelled by the sickly-sweet lullaby Isaac sings just before daddy's about to put him to the sword in Canticle II, then so haunted by the sombre war requiem of Britten's Edith Sitwell setting, Canticle III? Ambivalence about Ian Bostridge's weird dominating presence and Neil Bartlett's marshalling of five responses to the five very different narratives doesn't make it any easier.

"Britten or Poulenc?" The question may seem a fatuous one, geared to the 100th anniversary of the Englishman's birth and 50 years since the Frenchman's death. Yet it certainly livens up what would otherwise be the usual dreary artists' biographies, presented with typical elan in this year's Cheltenham Music Festival programme book. "Has anyone said Poulenc in response to this?" asks pianist James Rhodes.

Scotland’s East Neuk is a little like Hardy’s Wessex – less a geographical specific and more an idea, a resonance. Tucked up into the crook of the Firth of Forth, directly below St Andrews, the region encompasses the tiny coastal towns of Crail, Pittenweem, Anstruther and St Monans, where stern stone cottages and still sterner churches have done battle with the elements since at least the 9^th century.

It was an inspired Manchester International Festival initiative to devote a concert to the work of Sir John Tavener as he approaches his 70th birthday. Not only that, but the programme featured three world premieres, including a choral piece specially commissioned for the MIF Sacred Voices, made up of 70 women from all faiths and none. Leading it all with the BBC Philharmonic was conductor Tecwyn Evans.

It only takes a few great Lieder by Schumann and Liszt to show the kinds of songs Wagner didn’t, or couldn’t, write. Very well, so the rarities in this programme were whimsies he composed in his youth, but even the Wesendonck Lieder, sole voice-and-piano masterpieces of his maturity, don’t show much concern for the little details of humanity. Fortunately Janice Watson rose to great form to show us what, quite apart from the two "studies" for Tristan und Isolde, their opulent generalities are all about.

How often should a music-lover go to hear Britten’s most layered masterpiece? From personal experience, I’d say not more than once every five years, if you want to keep a sense of occasion fresh. So how often should an orchestra play it? Sir Simon Rattle and his Berlin Philharmonic decided they could manage three nights in a row towards the end of their 2013-14 season. At the first of the performances, it already felt like a lot might have been kept in check.
