Watch on Soap2day. From the “Arturo Toscanini” Auditorium in Turin, to celebrate the centenary of Luciano Berio’s birth, the RAI National Symphony Orchestra and its principal guest conductor Robert Treviño present “Folk Songs” for voice and orchestra, performed by mezzo-soprano Justina Gringytė. The second half of the evening features Dmitri Shostakovich’s Symphony No. 4 in C minor, Op. 43: one of the Russian composer’s most emblematic and experimental works.
