in early 2000, the website for the band, music70.com, removed the early discography of boards of canada, although some information has been preserved by fans. early tape releases by boards of canada include "play by numbers", "acid memories", "hooper bay", and the earliest known release by the band is titled "catalog 3". none of the material from those days is readily available, and since official boards of canada sources deny the existence of these albums, there seems to be little chance for this early material ever to be seen publicly.
