Twoism is the debut EP by Scottish electronic duo Boards of Canada, self-financed and released through their own Music70 record label in August 1995. Initially limited to 100 copies and released privately, the EP was reissued by Warp Records.
The EP led the duo to be noticed by Skam Records, resulting in the release of Boards of Canada's first major public EP Hi Scores in 1996 on Skam Records.
