The Gulbenkian Choir and conductor Jorge Matta present a programme with strong links to Portugal which is entirely dedicated to 20th century choral music. Alongside Nuits, by the Greek composer Iannis Xenakis – one of the masterpieces of the last century, commissioned by the Gulbenkian Foundation and premiered in 1968 – the concert includes pieces by the Portuguese composers Fernando Lopes-Graça, Joly Braga Santos and Filipe Pires. Finally, the mystical piece Libera me (1979), by the composer Constança Capdeville, who was born in Barcelona but settled in Portugal in 1951, is an inspired and expressive meeting point between the West and the East.
