Brutus was a Canadian rock band formed in 1969 and active, with interruptions, between 1969 and 1978.

The original band consisted of Walter Zwolinski as vocalist, Tom Wilson as bassist, Michael Magann on trumpet, Lance Wright on drums, Sonny Wingay on guitar, and Bill Robb on sax and trombone. The band was the opening act for popular Canadian and American acts that were touring Canada, such as The Guess Who. At one point, the level of band popularity was such that a recently-formed Chicago opened for Brutus at the University Of Waterloo, with Chicago's debut The Chicago Transit Authority album.[1]

Brutus disbanded in 1971, then reformed with a revised line-up and new look in 1973. They decided to add a theatrical flair to their stage act, similar to the glam rock bands that were popular in Britain during the same time. With a mixture of heavy makeup, wild costumes, and sexual innuendo, Brutus became a popular live act, but found few friends with the local authorities or concert organizers. Brutus' live performances reached a pinnacle with a sold out performance at Toronto's Ontario Place.

The new Brutus lineup recorded two singles on GRT Records in 1975, with "Ohh, Mama Mama" becoming their most successful recording, being named top Canadian single in an end-of-year poll by the Montreal Star. Their debut album would follow in 1976 but only two additional singles would follow before they disbanded.

Four notable guitarists associated with Brutus were Gino Scarpelli, later of Goddo, Paul Dean, later of Streetheart and Loverboy, Jerry Doucette, who has had a distinguished solo career, and John Bride, later of the Cameo Blues Band.
