The current line-up is formed of singer and performer Denis Gagné (Peter Gabriel), guitarist François Gagnon (Steve Hackett), bassist Sébastien Lamothe (Mike Rutherford), keyboardist Ian Benhamou (Tony Banks), and drummer Marc Laflamme (Phil Collins).

[2][3][4] Founding member and musical director, bassist Sébastien Lamothe, advertised in local newspapers for musicians who were Genesis fans to play in the band.

[3] The group initially performed as a seven-piece band and incorporated visual effects and costumes that were a part of Genesis's original shows.

In 1994, following the departure of lead singer and performer Marc Léveillé, the band recruited Denis Gagné as his replacement through a newspaper advert.

[7] Gagné immersed himself in the role of Gabriel, learning to play the flute, growing his hair long, and shaving a bald spot in the front of his hairline.

Since 2001, The Musical Box has grown in popularity, and has performed large sold-out shows in Canada, the United States, Europe and South America.

In 2004, the band secured the license to re-create Genesis's 1974–1975 tour that featured their double album The Lamb Lies Down on Broadway (1974) performed in its entirety, with encores.

[10] In 2013 and 2014, the band toured Selling England by the Pound in celebration of the album's fortieth anniversary, with some dates replaced with their Foxtrot show.
