Originally conceived as an aid to Menuck in learning how to score music,[7] the group has since blossomed into a regular collaboration.

When He Has Left Us Alone but Shafts of Light Sometimes Grace the Corner of Our Rooms... debuted, it was notable in that it included vocals by Menuck and his band mates; this was in contrast with the taciturn Godspeed You!

Zion Memorial Orchestra & Tra-La-La Band that Menuck did in fact sing vocals before the creation of the group on a "rare 1996 GYBE cassette release".

The topics of his lyrics range from the fear and loneliness experienced while driving alone on an American highway at night[9] to urban decay, and even a tribute to a deceased pet dog.

Zion Memorial Orchestra & Tra-La-La Band, was essentially created as a requiem for open and abandoned spaces in Montreal, as well as for similar loss and decay around the world, due to either urban development or military action.
