Masse was greatly influenced by the art and music scenes in Los Angeles and San Francisco, where he lived in the late 1960s, producing posters and album covers for various bands of the day.
With the rise of folk-rock, Vancouver played host to concerts from the Grateful Dead, Jefferson Airplane and the Steve Miller Band, with Masse contributing increasingly psychedelicized artwork for their appearances.
Returning to Vancouver, Masse, now a Scientologist, befriended the local band the Collectors, and when they travelled to Los Angeles to make a record he followed, spending the final years of the 1960s living in the Laurel Canyon area.
During the 1980s, Masse created posters for films including Total Recall and Back to the Future Part III; he also worked on the television series Teenage Mutant Ninja Turtles.
As rock concert art began to enjoy a surge in popularity during the following decade, however, Masse returned to poster design for the Smashing Pumpkins, Red Hot Chili Peppers, Tori Amos, Alanis Morissette, and others.
