On February 25, 2013, [[Trent Reznor]] announced that Eustis would be part of the touring lineup of Nine Inch Nails. It is assumed that he was originally slated to focus on keyboards, but was utilized mainly for bass on the [[NIN 2013 Festival Tour]], as [[Eric Avery]] had left the lineup. [[Pino Palladino]] was added to the lineup on bass for the [[Tension 2013 Tour]] and Eustis became a multi-instrumentalist, handling guitar, keyboards, backing vocals and saxophone.
Eustis also has prior ties to NIN, as he assisted with programming and sound design for the NIN track "[[The Great Collapse]]" and worked on remixes of "[[The Frail]], "[[Where Is Everybody?]]" and "[[Even Deeper]]". He also provided additional backing vocals on "[[I Would For You]]".
