With the concert on Friday 19th at 9.15 pm in the Oratorio di San Giuseppe in Piazza Antelminelli, Cluster’s Spring Season concludes in Lucca. A series of eleven concerts are all dedicated to contemporary music, written mainly by its twenty-four members who are part of this big “family” music. The group is mostly from Lucca, with compositions and productions such as on Friday the 19th, where there’s a duo composed by baritone Peter Paul and pianist Gerd Rosinsky. The concert is part of an exchange, with Cluster present in Berlin this May through the music of its president, Francesco Cipriano. The evening’s program, with free admission, includes performance of German music alternating with pieces by Cluster members Arduino Gottardo and Guido Masini.
