While attending art school in Vancouver, British Columbia, he began his career doing posters for the folk acts that came through town, in exchange for free drinks, tickets, and the opportunity to meet the musicians.
As folk became folk-rock, and Vancouver was visited by such bands as the Grateful Dead, The Doors, the Jefferson Airplane, and Steve Miller, Bob continued to produce memorable concert posters for these bands, and helped pioneer the emerging psychedelic art genre. He was greatly influenced by the art and music scenes in Los Angeles and San Francisco, where he spent considerable time in the late 1960s.
Masse befriended the Vancouver band, the Collectors, and when they traveled to Los Angeles to make a record, he followed, spending the final years of the 1960s living in the Laurel Canyon area, producing posters and album covers for various bands of the day. His work from this time is highly sought by collectors.
Bob’s designs reflect his interest in the art nouveau movement and the work of Alphonse Mucha in particular. While he employs many of the techniques of that period, his brilliant color palette, unique lettering style, and bold composition give his art a signature look.
