Sixtoo (aka Six Vicious, Speakerbruiser Rob) was the main project of Canadian hip-hop DJ, MC and producer Vaughn Robert Squire. He was born in 1978 in Halifax, Nova Scotia, Canada. He came out of the mid-90's underground hip-hop scene sharing the stage with such notable Canadian hip-hop artists as Buck 65 (with whom he formed Sebutones) and members of the Anticon crew. This period lasted until he moved to Montreal in 2000 where he signed with UK-based label Vertical Form Records.
