In 1994, Clarke was replaced by Rose's childhood friend and Hollywood Rose collaborator Paul Tobias. Around this time, Rose became "obsessed" with electronica and industrial rock, particularly the work of Nine Inch Nails, and wanted Guns N' Roses to move towards a more contemporary musical direction. Other members of the band did not agree with style change, causing a rift. Slash left in 1996 following creative differences with Rose and personal problems with Tobias. New band members were auditioned, including guitarist Zakk Wylde and drummers Dave Abbruzzese and Michael Bland. Slash was replaced in January 1997 by former Nine Inch Nails touring guitarist Robin Finck. In April 1997, drummer Matt Sorum was fired after an argument with Rose about Tobias's inclusion. Former Nine Inch Nails drummer Chris Vrenna worked with the band for a few months shortly afterward.
