Bayard Rustin is a fascinating but little-known figure in US history: a civil rights organiser who worked behind the scenes on both the Montgomery bus boycott and Martin Luther King’s 1963 March on Washington, as well as campaigning for pacifism (he was on the British anti-nuclear Aldermaston March in 1958) and gay rights. He was also an accomplished singer and lutenist, and advocate for Elizabethan song repertoire.

Perfectly at one in matching tone and response, this phenomenal duo who are both formidable solo personalities in their own right also took us through a range of colours and approaches in a cornucopia of masterpieces for both four hands at one piano and two instruments placed side by side, from Bach to Lutoslawski, Debussy to Tailleferre.

Two concerts packed with thorny repertoire playing to large and enthusiastic audiences of all ages: the London Philharmonic Orchestra is cresting a tricky wave right now. A fortnight ago Conductor Emeritus Vladimir Jurowski held us spellbound with mechanistic Mosolov and Prokofiev (the insanely difficult Second Symphony); last night Principal Conductor Edward Gardner served up Czech and Polish rarities, drawing equal fire from the players. Proof indeed that the successor was the right choice.

On a dank January evening in St Albans, there seemed little sign of life or excitement on the streets. To reach my destination – St Peter’s Church – I first had to walk through an ancient graveyard where the yew trees loomed like sentinels. It was quite a contrast to enter the church itself, where the sudden blaze of light and warmth and packed aisles made it clear that this, for tonight at least, was the heartbeat of St Alban’s.

There is nothing to compare with the visceral experience of hearing a massed choir – in this case the 230-strong combined forces of the Crouch End Festival Chorus and the Hertfordshire Chorus – in full-throated fortissimo. Add in a team of stellar soloists and an inspirational conductor and the result was a very enjoyable musical evening at the Royal Festival Hall.

The cellist and the pianist famously have a more competitive relationship in Brahms’ Cello Sonata in E minor than in many compositions for solo instrument and piano. Brahms composed it for the Viennese singing teacher and cellist Dr Joseph Gänsbacher – when, on first playthrough, Gänsbacher complained he couldn’t hear himself because of the piano part, Brahms bellowed back, “You’re lucky.”

Any conductor undertaking a journey through Mahler's symphonies - and Vladimir Jurowski's with the London Philharmonic Orchestra has been among the deepest - needs to give us the composer's last thoughts, not just the first movement (which, along with the short "Purgatorio" at the centre of the symphony, was all that Mahler fully scored). Or so I thought every time I heard Deryck Cooke's restrained but not anaemic performing version.

Perhaps it was the thought of “Blue Monday”, which fell a week ago, that stimulated the choice of Lili Boulanger’s D’un soir triste as the opening piece of this concert. Certainly there can be few short pieces of music filled with such unremitting misery from start to finish.

It was a pleasure to see conductor Duncan Ward back in Manchester. His Hallé debut was by no means his first time in the city – he trained at the University of Manchester and the Royal Northern College of Music and has conducted the BBC Philharmonic and Manchester Camerata in the past, and some may even remember him as a student with an orchestra he took to the Arndale shopping centre, making music in the malls, back in 2011.

Every visit by Vladimir Jurowski, the London Philharmonic Orchestra's former Principal Conductor and now Conductor Emeritus, is unmissable, and this fascinating programme outdid expectations.
