During this concert, organist Ere Lievonen will perform a number of new 31-tone works. Among others, the Flemish composer Bert Van Herck and the Dutch composer Christina Oorebeek were commissioned to write new pieces for the Fokker organ. In addition, an older work (2002) by Sander Germanus for this microtonal instrument will receive its premiere, performed entirely via laptop. Early music will also feature in the programme, with early Baroque compositions by the little-known but forward-looking composers Ascanio Mayone, Giovanni Maria Trabaci, and Tarquinio Merula, whose music is particularly well served by the meantone tuning of the unique Fokker organ.
