Changes

This is the original album version. Beginning immediately with Dave Grohl's quick drumming, the song is differentiated as the only studio [[NIN]] song featuring prominent double bass technique. Joined by panning noise loops, a distorted guitar riff and echoing synthesizers, [[Trent Reznor]] delivers each verse in yells, a delay effect bouncing his voice throughout the mix. The chorus opens up considerably, simplifying the drum rhythm and featuring loud, distorted bass frequencies. The bridge maintains the quick intensity of the verses but builds up using a new bassline and the repeated mantra, "Remember where you came from. Remember what you are." The final chorus is even louder than the first two, culminating in a wah guitar ending that gives way to quiet synthesizer chords accompanying the chorus piano line. The end of the last musical phrase segues into "[[The Collector]]."The descending guitar melody during the bridge is very similar to that during the verses of "[[Everything]]".

"You Know What You Are?" made its live debut on [[2005/03/23 Fresno, CA|March 23, 2005]] and became a staple of [[Nine Inch Nails]]' ''With Teeth''-era live performances. The song, when performed live, sounds very similar to the album version. The only significant differences are the improvisational soloing by [[Aaron North]] during the bridge and the more sudden ending, exemplified on ''Beside You In Time.''
