In "Le monde d'hier", bassonist Mathieu Lussier and pianist Francis Perron explore French and English repertoire for bassoon written at beginning of the 20th century.

The composers recorded here, including Elgar, Gounod, Massenet, and Saint-Saens, fully embraced the Romantic movement of their era. Gabriel Pierne's almost jazzy Solo de concert rubs shoulders with the noble and introspective Romance by Edward Elgar. Lussier has also chosen grand sonatas by Camille Saint-Saens and William Hurlstone, as well as smaller works and short vignettes by Herbert Howells, Eugne Bourdeau, Charles Gounod, Jules Massenet, and Philippe Gaubert.
