On her second COBRA album Nuala McKenna has once again made a selection of particularly beautiful 20th-century pieces which also show her exceptional talent as a cellist. She is here to be heard in a duo together with Robert Kulek. All three composers wrote the works brought on this album DUO in disturbing and turbulent times; during a world war.

Bohuslav Martinů's Cello Sonata no.1, premiered in 1940, is an exciting, dramatic work and the melodies with a Czech character convey his nostalgia for his homeland. Martinů was persecuted by the Nazi regime because of his ties to the Czech resistance movement and thus he fled to the United States with his family in 1940. He called the premiere of his First Cello Sonata the 'last greeting from a better world'.

Francis Poulenc's safety was endangered during the Nazi regime due to his homosexuality and his ties to the resistance movement 'Front National des Musiciens' which had close connections to persecuted musicians such as Milhaud and Hindemith. Poulenc composed his Sonata for cello and piano in 1940 shortly after being discharged from military service following France's capitulation to Germany. It took another eight years for the composition to be completed so that it could be finally premiered in 1949. The Sonata was received with little enthusiasm. Some critics rated it as 'pleasant but nothing more...'.

Paul Hindemith's early works 3 Pieces for cello and piano, op.8, was composed in 1917, the third year of World War I, shortly before being drafted into military service. Between 1913 and 1920, disturbing times and his circle of young conservatory friends inspired Hindemith to write a total of seven so-called 'dramatic masterpieces' - whimsical, almost surrealistic pieces whose subjects usually have an autobiographical background. Later he dismissed his works from this creative period as 'unbearable', but towards the end of his life he saw these works in a different perspective and attempted to publish them.
