new nasty aphex remix/remash from rephlex site

anyone heard this yet? http://www.rephlex.com/mp3/boxenergy4remix1.mp3 just found it today on the rephlex site... curious if anyone has any info on it... mashed up (or maybe live?) version of one of the fast bleepy druqs tracks or one of those "2 remixes by..." tracks... I forget the name right now. Worth a listen if you like the fast stuff.
