He was also a keyboard player in the earliest incarnation of the NIN live band in 1988. A new keyboard player was then brought on board so that Vrenna could switch to drums. 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" (live) and "[[The Perfect Drug (song)|The Perfect Drug]]".
After leaving NIN, Vrenna formed the band [[Tweaker]]. The band has three full-length albums entitled ''The Attraction to All Things Uncertain'', ''2 A.M. Wakeup Call'' and ''Call The Time Eternity''. Vrenna's inspiration is derived mainly from surreal paintings and dreams.
