'''Chris Vrenna''' (born February 23, 1967) was the live drummer for [[Nine Inch Nails]] from 1989 to 1997 (except for 1991, when he was fired from the band for a brief period). He met [[Trent Reznor]] in Cleveland, Ohio, in the mid-1980s when they were roommates and both played in a local band called the [[Exotic Birds]]. Additionally, Vrenna has been credited as an engineer for ''[[Pretty Hate Machine]]'' and ''[[The Downward Spiral (halo)|The Downward Spiral]]'', as well as playing live drums on the latter. He can be seen in the music videos for "[[Down In It (song)|Down In It]]", "[[Head Like A Hole (song)|Head Like A Hole]]", "[[Wish (song)|Wish]]", "[[Gave Up]]", "[[March Of The Pigs (song)|March Of The Pigs]]", "[[Hurt (song)|Hurt]]" (live), "[[Eraser]]" (live), "[[Wish (song)|Wish]]" (live) and "[[The Perfect Drug (song)|The Perfect Drug]]".
After leaving NIN, Vrenna formed the band [[Tweaker]]. The band has two full-length albums entitled ''The Attraction to All Things Uncertain'' and ''2 A.M. Wakeup Call,'' as well as a new album due out in 2008. Vrenna's inspiration is derived mainly from surreal paintings and dreams.
