Enshrined in the Guinness World Records as the largest jazz festival in the world, the Festival International de Jazz de Montréal has, for over 30 years, transformed the city into a meeting place for enthusiasts of all music related to jazz. For 10 days, the Festival relies on the presence of nearly 30 countries, 3,000 musicians and buskers, 800 concerts (of which two thirds are free), 600 activities and performances, 15 indoor venues, 10 outdoor venues, and 2.5 million visitors.
