aphex twin's two contributions to "further down the spiral" are not remixes but rather new works composed specifically for the album. aphex twin is the performance moniker of british electronic musician richard d. james, who was quoted about his various "remixes" as saying "i never heard the originals, i still haven't. i don't want to either, or my remixes for that matter." both tracks would later appear in shortened form on aphex twin's 2003 compilation "26 mixes for cash". "at the heart of it all" shares its name with a coil piece from their 1984 lp "scatology".
