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.
