Verdigris – also known as copper(II) acetate, the deposit that makes a green patina on metals such as bronze. Composing is nothing more than adding these kinds of layers to the history of music, says Lotta Wennäkoski. That’s why she calls her homage in sound to her great compatriot Jean Sibelius «Verdigris».

But between these two performances, Katharina Hörmann delights in a musical late vintage: Richard Strauss’s Oboe Concerto, written in 1945 for a US soldier.
