==Work with NIN==
Hillebrandt was listed as a member on NIN in a 1997 ''Kerrang!'' interview. [https://groups.google.com/g/alt.music.nin/c/cJlN2GKF4GA/m/SU1yRq3BDGoJ] On David Bowie's ''[[I'm Afraid Of Americans]]'', Hillebrandt is listed as a full member of NIN along with [[Dave Ogilvie]], [[Danny Lohner]] and [[Charlie Clouser]]. He was evidently planned to be part of a multiple-keyboardist setup for the live band that [[Trent Reznor]] originally put together for the [[Fragility]] tour, but ''[[The Fragile (halo)|The Fragile]]'' took a different route sonically and this idea was scrapped, although he did replace Charlie Clouser during the [[CRC Sessions]].
He ended up becoming an in-house programmer for Reznor from 1997-2002, and created an entire library of sounds towards use on ''The Fragile''. This was detailed in an article[http://www.nin-pages.de/2004_Apple_Hillebrandt_english.htm] from Apple:
