"Indifférence" is a classic valse musette composed in 1942 by accordionist Tony Murena and co-signed by Joseph Colombo. This piece has become a standard in the musette and gypsy jazz repertoire, celebrated for its emotive melody and waltz rhythm. Although Django Reinhardt did not record "Indifférence," its expressive character and intricate harmonies have made it a favorite among gypsy jazz musicians, who continue to interpret and perform the piece, keeping its legacy alive within the genre.
