A first live experience of the French-Cameroonian singer Sandra Nkaké leaves many questions unanswered. Once the immediate bewilderment has passed, the most pressing question for a British audience should be: why is this extraordinary performer not block-booking the festival circuit? In a single set, accompanied by flautist and controller of the electronics, Jî Drû, Nkaké gave a stunningly complete display, as voice, accompaniment, movement and stage presence combined to project her mesmerising, leonine charisma.

Since self-releasing his debut album Heard It All Before in 1999, Jamie Cullum has gone on to become the UK's biggest selling jazz artist of all time. Since April 2010, he has also presented a weekly jazz show on BBC Radio 2, for which he won a Sony Gold award this year.

“Wildern” means “poaching” in German. That’s as in pheasant, rather than egg. On this album, German jazz singer Tobias Christl goes poaching (foraging might be more accurate) for iconic rock songs, which he adapts for his jazz quintet. Retaining on some level the basic emotional character of the song, he otherwise manipulates freely, to the point where in a couple of cases it’s not obvious which song he started with.

“Were we leaving Rio, or were we in New York?” Stacey Kent sings in “The Changing Lights”, the title song of her latest album, before moving on seamlessly to “Les Invalides, or Trafalgar Square”. The prosperous, wistful ennui that some of her recorded songs exude, propelled by her impeccable enunciation and glistening tone, is cosmopolitan with a slightly laminated, departure-lounge sameness. It can feel a little bit like a global franchise in polite enervation.

Acclaimed British jazz singer Georgia Mancio celebrates five years of ReVoice!, her festival of jazz song, with an expanded event – now twice its original length – beginning next week. Mancio’s programming combines some of the most charismatic and original performers worldwide to create ten concerts (some with several performances) that display the art of jazz singing at its cosmopolitan best.

Amy Winehouse, Esperanza Spalding, and Roberto Fonseca were the names tossed and bandied after a London debut of extraordinary charm and maturity from the 19-year-old Spanish singer and multi-instrumentalist Andrea Motis. While a modest Soho crowd was dwarfed by the audience at the Barcelona Jazz Festival where she became, in 2012, the youngest performer to headline, there was a communal tingle of recognition, that we’d witnessed the start of something big.

Sun Ra and his Arkestra: In the Orbit of Ra

Recorded in the UK, Johannesburg, Paris and Tel Aviv, Sarah Jane Morris's latest album, Bloody Rain, is undoubtedly a labour of love. Hearing it performed live last night in the Union Chapel, in front of an adoring audience, confirmed that it is also her masterpiece.

It was Jim Jarmusch’s film Broken Flowers that first really got Mulatu Astatke major Western attention – in same way that Angelo Badalementi’s music for Twin Peaks gave a rich and strange dimension to David Lynch’s TV epic, there was an even greater sense of wonderful disorientation, or as Brian Eno put it “jazz from another planet,” with Astatke’s music.

Aaron Copland was an unlikely musical portraitist of the American plains and prairies. Son of Jewish immigrants from Brooklyn and student of modernism with Nadia Boulanger in Paris, he nonetheless created the quintessential American orchestral sound with a series of popular (“vernacular” was his phrase) works in 1930s and 1940s. Last night three of his most popular pieces were paired with two new pieces inspired by jazz, that other great American twentieth-century music.
