The band's initial lineup included Reznor on vocals and guitar, Chris Vrenna on keyboards, programming, and percussion, and Ron Musarra on drums.
[2] For the next tour, which started in late 1989, Musarra was replaced on drums by Vrenna, and the lineup was expanded with guitarist Richard Patrick and a new keyboardist.
In 1994, for the Self Destruct Tour, Danny Lohner and Robin Finck replaced Patrick as new bassist and guitarist respectively (although both members handled other instruments as well).
At that point, Vrenna departed for the second and final time and Jerome Dillon joined as his replacement on drums,[10] alongside a returning Finck on guitar.
The lineup featured Reznor and Dillon, in addition to new members Aaron North on guitar, Jeordie White on bass, and Alessandro Cortini on keyboards.
During the band's first arena tour in the US, Dillon was forced to retire due to a medical condition,[11] and he was briefly replaced by Josh Freese, and then by Alex Carapetis.
[18] Nine Inch Nails returned to a live setting in 2013,[19] announcing a tour for 2013 with new members Eric Avery (bass), Adrian Belew (guitar), and Josh Eustis (keyboards/guitar).
