Approximately every 20 years, the ‘once in a generation’ Fête des Vignerons takes over the Swiss town of Vevey for a month in July and August. Featuring 6,400 performers, musicians and singers, 2,000 lighting fixtures, 612 loudspeakers and over 300 channels of wireless microphones, 11 Yamaha digital mixing systems were needed for the centrepiece production of the 2019 event.
