Faced with yet another new work premiered by the Borodin Quartet, Shostakovich asked a daunting question: "but have you played all of Haydn's quartets yet?". Of course they hadn't, and felt justly rebuked.

This time of year lots of choirs give lots of Christmas concerts that are more or less the same: traditional repertoire perhaps sprinkled with a few novelties. But Tenebrae’s concert on Saturday at Kings Place broke the mould with some imaginative programming, giving us just enough Christmas but no more, and some quite stunning choral singing.

Peter Phillips and the Tallis Scholars have nothing to prove when it comes to Renaissance choral music – few ensembles can match them for clarity, balance and purity of tone. They are perfect guides, then, for this tour of the late Italian Renaissance, an era, as they demonstrate, of surprising musical variety and fast-changing tastes.

Reformation Day, Luther 500 - in Proms terms it can only mean Bach, the alpha and omega of music, flourishing roughly two centuries after the Wittenberg Nightingale nailed his 95 theses to the church door.

From sunset to sunrise, across aeons of time, usually flashes by in Schoenberg's polystylistic epic. Not last night at the Proms: Simon Rattle is too much in love with the sounds he can get from the London Symphony Orchestra - here verging on a Berlin beauty - to think of moving forward the doomed love of Danish King Waldemar and the beautiful Tovelille.

So it was Rachmaninov night at the Proms, but with a difference: a trinity of works sacred and profane, the first two introduced by the Latvian choir due to perform the third singing harmonised Russian Orthodox chants of the kind on which the composer based so many of his supposedly late-romantic inspirations. That was bound to enliven a bog-standard programme of the Third Piano Concerto and the Second Symphony.

On a dreary evening in what passes for summer, the news unutterably grim, an evening in the company of South Africa’s greatest export can’t help but lift the spirits. The nine singers that comprise Ladysmith Black Mambazo are mostly blood family, sons of Joseph Shabalala - who founded the group in 1960 following a series of dreams in which he heard traditional Zulu isicathamiya - their cousins and two friends, and what an amazing stage act they are.

Sacred and profane, trivial and profound blissfully combine in this irresistible, Olivier Award-winning tale of choirgirls gone wild. Lee Hall, of Billy Elliot fame, adapts Alan Warner’s 1998 novel with a similarly shrewd grasp of youthful hope amidst challenging circumstances, and with the arts once again proving a vital escape – albeit, in this case, temporarily.

On paper this was a knockout concert: Gramophone Award-winning Belgian ensemble Vox Luminis teaming up with the wonderfully gutsy Freiburg Baroque Consort to perform Monteverdi’s Vespers in the composer’s 450^th anniversary year – one of the highlights of this year’s London Festival of Baroque Music.

This is a bit of a curiosity. Kasai Allstars were bought to our attention by producer Vincent Kenis almost a decade ago, after he’d had great success with those masters of the amplified thumb piano cacophony, Konono 1.
