Kassé Mady Diabaté is one of the great singers of West Africa, a member of Toumani Diabaté's Symmetric Orchestra and, more recently, the Afrocubism all-star line-up. His latest album Kiriké (Horse’s Saddle) on the Parisian No Format label is a beautiful return to his acoustic, traditional roots as a singer, produced by French cellist Vincent Segal and featuring kora maestro Ballaké Sissoko, Lansiné Kouyaté on balafon and Makan Tounkara on ngoni, conjuring up the spirits and messages of centuries-old Bambara songs of the ancient Manding Empire. This music runs deep.

Paying homage to the legendary imprint that brought us 'The Finest In Jazz Since 1939', this concert on the penultimate evening of the EFG London Jazz Festival really did have everything, including the unlikely sight of master pianist Robert Glasper pirouetting across the Royal Festival Hall stage. The first half saw Glasper in duo with fellow NYC-based Houstonian, pianist Jason Moran, in an extraordinary, hour-long set that referenced jazz past, present and future.

John McLaughlin made history at the Royal Festival Hall 25 years ago when he recorded a superb album featuring Indian percussionist Trilok Gurtu. Last night’s performance with his fusion quartet 4th Dimension was not epochal in quite that way. The repertoire and style was largely familiar, much of it released on the band’s album earlier this year, the pieces in many cases reworked from earlier McLaughlin material. But it was remarkable for the excellence and of the ensemble playing.

It has always been obligatory when talking about Steve Martland to describe him as an iconoclast. Before his sudden death in May 2013 at the age of 58, he forged a reputation for himself as a self-styled outsider to the musical establishment, speaking scathingly about the Proms, and eschewing established orchestras and ensembles in favour of writing for his eponymous band. Members of that band joined Colin Currie and the Aurora Orchestra to pay spirited homage to Martland, and place him in his musical context.

Even the cold breeze along the Thames played its part in conjuring the chilly, epic Finnish landscapes of Jean Sibelius last night, though Finnish maestro Osmo Vänskä and the perfectly weighted phrasing of the London Philharmonic Orchestra can take primary credit. It’s unusual to have a single-composer programme these days, but Vänskä justified his repertoire with a performance of taut, lyrical and evocative power, which connected and illuminated different areas, historical and generic, of Sibelius’ career.

Arcadi Volodos is a relatively rare visitor to London these days. Although the Russian pianist, 42, rose early to fame, his development has perhaps taken him in a direction that startles those who were initially seduced by the astounding virtuoso transcriptions – many of them his own – in which he initially established his reputation.

This concert was part of a tour of Canada’s National Arts Centre orchestra to five cities in the UK themed around the anniversary of the start of World War One. The Ottawa-based orchestra joined forces with the Royal Philharmonic Orchestra and the London Philharmonic Choir for this London centrepiece to the tour, under the baton of violinist-turned-conductor Pinchas Zukerman.

Pianist Mitsuko Uchida's concentration, calm and grace under pressure are an inspiration. Towards the end of the first piece on her programme, played to a packed Royal Festival Hall last night, the quiet but insistent high-pitched screech of a fire alarm kept going off. Low voices on walkie-talkies at the entrances to the hall were also audible. Whatever the confusion they were sharing with each other, they were failing to lift it.

What Anne-Sophie Mutter is to the violin, Alison Balsom to the trumpet and Sabine Meyer to the clarinet, so is Sioned Williams to the harp. Though Meyer had the glass-ceiling distinction of being the first woman in the Berlin Philharmonic, Williams’s service to the BBC Symphony Orchestra has been longer (nearly 25 years so far as principal harp). And while all four artists have had major new works composed for them, the harpist’s commission of six pieces to celebrate her 60th birthday would seem to be a record.

London homelessness charity The Passage was set up in 1980 and has been growing steadily so that it now provides a day centre, short-term hostel and long-term housing in an effort to help street sleepers get their lives back on track. Its annual "A Night Under the Stars" gala concert is the central event on its fundraising calendar, and assembles an extremely high standard of musician. The evening was compered by Jo Brand and Petroc Trelawny, both safe pairs of hands in their distinct ways.
