Finck grew up in
Marietta, Georgia and played with several unsigned bands based primarily in the
Atlanta area, including acts such as Prowess, Bat Your Lashes, Sik Dik (bandmates of which included Steve "Holiday" Childress and Michael Allen, currently of The Goodies and Greg Thum), and The Hookers. He joined
Nine Inch Nails as part of their
touring band in 1994–95 for their
Self-Destruct and
Further Down the Spiral tours following the departure of previous guitarist
Richard Patrick. Finck appeared with Nine Inch Nails at
Woodstock '94, Once the tour was completed, he took a job playing for the circus troupe
Cirque du Soleil in the original tour of
Quidam. Finck rejoined Nine Inch Nails as the band embarked on their
Fragility v1.0 and
Fragility v2.0 tours in support of the 1999 album
The Fragile. Shortly after the tour ended in 2000 he returned to Guns N' Roses, playing four shows with them in late 2001 followed by a brief tour of Europe and Asia in mid-2002 and a live appearance at the MTV Video Music Awards. A planned US tour was meant to continue through the remainder of 2002 but was called off by the promoter after two cancelled shows led to rioting by fans. Around this time Finck and then-bandmate
Buckethead contributed to the soundtrack of the John Carpenter movie
Ghosts of Mars, playing alongside members of thrash metal group
Anthrax and guitar virtuoso
Steve Vai. After his touring obligations with GNR were fulfilled he joined the LedZAerial production (a performance by acrobats set to the music of the band
Led Zeppelin). Finck was invited to rejoin NIN to tour in support of their 2005 album
With Teeth but chose not to and the position was filled by
Aaron North. In the summer of 2006, he toured Europe with Guns N' Roses playing in front of over 700,000 people. They finished up by touring North America for the remainder of the year, and went to Mexico, Australia, New Zealand and Japan in 2007. On April 4, 2008, it was announced via nin.com that Finck would be rejoining
Nine Inch Nails as a member of the live band. He subsequently contributed to the
Nine Inch Nails album
The Slip, earning a performance credit alongside then-band members
Josh Freese and
Alessandro Cortini. In November 2008 Guns N' Roses' long-awaited album
Chinese Democracy was released. Finck has a co-writing credit on the song "Better", which was later released as a single, as well as 7 other songs on the album. He also played guitar on every track, performed 7 of the guitar solos and has additional credits for keyboards, arrangements and pre-production. He chose to remain with NIN after the album's release and, on March 21, 2009, was officially replaced as the lead guitarist of Guns N' Roses by
Sixx:A.M. guitarist
DJ Ashba. The official
Guns N' Roses website stated that "Robin continues to be part of GN'R, by virtue of Guns' history and his involvement in Chinese Democracy". Finck appears on the 2010 album
The Lady Killer by artist
CeeLo Green, performing guitar on the track "The Lady Killer Theme (Outro)". On March 12, 2012, Finck appeared on-stage with Guns N' Roses, performing "
Better", a song he co-wrote with Axl Rose. Finck rejoined
