More than 1,200 international stars including Elton John, Johnny Hallyday, Françoise Hardy, Julio Iglesias and Chris de Burgh have signed a petition being presented to the EU calling them to cut VAT on CDs - currently set between 15% and 25% depending on the country.
To be presented in Brussels on Tuesday, the petition requests that music to be classed in line with other cultural products such as books, newspapers and theatre tickets, which have reduced VAT rates.
Callier, from the band Hooverphonic, told reporters: " When someone buys a biography of Jacques Brel in Belgium he pays a VAT rate of 6%, but if he buys a CD of his music he has to pay 21%. This makes no sense and does not recognise the cultural role of musical artists."
