On Sunday 12 September 2010, a special concert on the Fokker organ will take place in the BAM Hall of the Muziekgebouw aan ’t IJ as part of the Gaudeamus Music Week. No fewer than ten premieres are on the programme, with eleven composers having created works specifically for this occasion. These microtonal compositions will be performed either by organist Ere Lievonen or via laptops, sometimes supplemented with audio. The composers are Janco Verduin, Steffen Krebber, Hector Bravo Benard, Martin Lo-A-Njoe, Michiel Mensingh, François Gabriel Madden, André Douw, Sean Winters, Christian Pfeiffer, Joseph Michaels, and Iván González Escuder.
