Play By Numbers is the name of Boards of Canada's fourth known release. The Jockey Slut article by Richard Southern describes Play by Numbers as follows: "Five-track CD from what was now a trio, boasting a My Bloody Valentine influence in places, shifting further into electronics in others." It has also been said that the album, "with the 9-minute Infinite Lines of Colourful Sevens, showcased a more creative approach."[1]
Of the album's five tracks, only a 56-second excerpt of Wouldn't You Like To Be Free (posted on the EHX website in the late 1990s) has been heard by those outside of the band's friends and family.
