Deja Voodoo was a two-man band from the early to late 1980s, composed of Gerard van Herk and Tony Dewald. Based in Montreal, Quebec, they played a stripped down version of garage rock mixed with rockabilly, heavily influenced by the likes of The Cramps, that they called sludgeabilly. They played fast, short songs about such things as monsters, money, and bugs.
While never enjoying significant national chart success, the band was very popular with Canadian alternative campus radio stations. Their main influence on the Canadian alternative music scene was their launching of the Og Music record company, which was home to many other influential Canadian alternative bands, including the Gruesomes and Ray Condo. Their It Came from Canada compilations helped launch the careers of Shadowy Men on a Shadowy Planet and Cowboy Junkies. In addition, the band were noted on the Canadian music scene for their annual "Deja Voodoo BBQ", an annual event in Montreal featuring a barbecue and a concert lineup of independent bands.
The band and the label were retired when the band members turned thirty years old, and they left the music business to pursue other careers. They reunited briefly in 2006 to stage a reunion BBQ show at Toronto's Silver Dollar club.
