Intelligence and Sacrifice is a 2001 album by German recording artist Alec Empire. While by no means his first solo album, it was his first full album since the demise of his former band Atari Teenage Riot, and he regarded it as a new beginning, stating that it "feels like this is my first real album". This recording consists of two CDs, each with a significantly different sound. CD 1 is somewhat consistent with the ATR formula while the second disc (printed on the album cover as CD²) is entirely electronic with negligible use of vocals.
"Tear It Out" (Remix) is an alternate version of a track originally intended for Dave Grohl's Probot project. The project consisted of instrumental tracks recorded by Grohl, with vocals provided by several well-known heavy metal singers. When Probot was finally released, Empire's contribution was not used. Instead, the track was re-recorded with new lyrics and vocals by Mike Dean of Corrosion of Conformity and it became known as "Access Babylon".
