Please answer the following question: Given the following context:  In support of Nine Inch Nails' third full-length studio album, The Fragile, the live-band reformed for the Fragility tour.  The lineup remained largely the same from the Self-Destruct tour, featuring Finck, Clouser, and Lohner.  To replace long-time member Vrenna, Reznor held open auditions to find a new drummer, eventually picking then-unknown Jerome Dillon.  Dillon would remain a member of the live band until 2005. Nine Inch Nails' record label at the time, Interscope Records, reportedly refused to fund the promotional tour following The Fragile's lukewarm sales.  Reznor instead committed himself to fund the entire tour out of his own pocket, concluding that "The reality is, I’m broke at the end of the tour," but also adding "I will never present a show that isn’t fantastic."The Fragility tour began in late 1999, running until mid-2000, and was broken into two major legs, Fragility 1.0 and Fragility 2.0 respectively.  Destinations included Europe, Japan, New Zealand, Australia, and North America.  Before the first Fragility performance date in Spain, Nine Inch Nails opened their final rehearsal in London to 100 fans. Kick-starting the tour was a performance of the title track from The Fragile at the MTV Video Music Awards.  Atari Teenage Riot opened for Nine Inch Nails during Fragility 1.0, and A Perfect Circle for Fragility 2.0.  At the time, A Perfect Circle featured Josh Freese on drums, who would later replace Dillon and play drums for Nine Inch Nails from 2005 to 2007. The tour featured increasingly large production values, including a triptych video display created by contemporary video artist Bill Viola. Rolling Stone magazine named Fragility the best tour of 2000.In 2002, the tour documentary And All That Could Have Been was released featuring a collection of performances from the Fragility 2.0 tour.  While making the DVD, Reznor commented on the tour in retrospect by saying "I thought the show was really, really good when we were doing it", but later admitted that he "can't watch [the DVD] at all....  answer the following question:  What was the name of the drummer on the Self-Destruct tour?
