No Music Day (November 21) is an event introduced by Bill Drummond to draw attention to the cheapening of music as an art form due to its mindless and ubiquitous use in contemporary society.
This follows the traditional observance of antithetical events on the day before religious occasions, such as celebrating Mardi Gras before the start of Lent.
It was launched in 2005 with a billboard poster at the entrance to the Mersey Tunnel, Liverpool.
No Music Day was promoted in São Paulo, Brazil in 2008, although Drummond has stated that despite graffiti announcing the day, his efforts to apprehend buskers and to encourage music shops to close, he doubted that "there was even a fraction less music consumed in Brazil on the 21 November 2008 compared to any other day.
Shops, restaurants, schools and radio stations in Linz played no music, the cinemas showed only films without music soundtracks and theatres and concert halls held only non-musical performances.
