Further Down the Spiral is the first remix album by American industrial rock band Nine Inch Nails. It is the companion remix disc to the band’s second studio album, The Downward Spiral, and was released on June 1, 1995 in two editions, one denoted as Halo 10 (released in the United States and in the United Kingdom on the morning of release, to be pulled and replaced with Halo 10 V2 by lunch time) and the other as Halo 10 V2 (released in Japan, Australia, and the UK), each containing a different set of tracks.
"At the Heart of It All" and "The Beauty of Being Numb"
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.
