The concert was recorded on June 20, 1977, at a sold-out event at the Malkin Bowl in Vancouver, British Columbia,[3][2] during the band's lengthy L'heptade sur scène tour in promotion of the album.

[4][5] The content offered on the double discs was highly edited from the full, two-hour concert, truncating more than thirty minutes of material by removing much of the between-song French and English banter and explanations from Fiori (to a principally Anglophone audience).

[6][7][8] It also omits five songs from the show: the song "C'est dans le noir", which was performed as the opener on this tour (and not included on the studio album of L'heptade), as well as performances of "Un musicien parmi tant d'autres" from the band's debut eponymous album, Harmonium, and three (including "Dixie (Une toune qui me revient)") from its second release, Les cinq saisons, which were played as encores.

[11][12] A live album was later organized by the band's former manager, Paul Dupont-Hébert,[9] released on August 5, 1980 (after Harmonium's break-up),[13][14] in Canada by CBS Disques and in France by Spalax Records.

[21] Spanish record label Blue Moon Producciones Discográficas also released a double compact disc bootleg (this one packaged in a standard jewel case) as part of its PG series in late 2001.

[21] The band's former members and management, notably Locat and Dupont-Hébert, spoke out against the unauthorized releases to La Presse in March 2002, then engaged in a legal procedure to put an end to the bootlegs.
