Changes

Patrick spent two and a half years as the touring guitarist in NIN and can be seen in the [[Nine Inch Nails music videos|music videos]] for "[[Down In It (song)|Down In It]]," "[[Head Like A Hole (song)|Head Like A Hole]]," "[[Wish (song)|Wish]]," and "[[Gave Up]]." His only recorded contribution—a droning guitar sound—can be heard at the end of "[[Sanctified]]" on ''[[Pretty Hate Machine]].'' He chose to leave the band during the recording of ''[[The Downward Spiral (halo)|The Downward Spiral]]'' in 1993 due in part to [[Trent Reznor]] not allowing him any creative input or musical contributions, as well as often taking a lot of onstage physical abuse from Reznor. Patrick went on to form his own industrial rock band, [[Filter]], with fellow NIN collaborator Brian Liesegang (, though Liesegang left in 1997) and the band has released seven studio albums: ''Short Bus'' (1995), ''Title of Record'' (1999), ''The Amalgamut'' (2002), ''Anthems For The Damned'' (2008), ''The Trouble with Angels'' (2010), ''The Sun Comes Out Tonight'' (2013) and ''Crazy Eyes'' (2016).

In 2005 Patrick also formed the band Army of Anyone with the DeLeo brothers of Stone Temple Pilots and in late 2006 the band released their eponymous album. The band split a year later and Patrick returned to Filter. As of 2018, Brian Liesegang has rejoined Filterin 2018. Utilizing PledgeMusic, the pair began working on a musical sequel to ''Short Bus'' entitled ''reBus''. This was shelved in the wake of the PledgeMusic scandal and Patrick stated that he was working on another new Filter album, tentatively titled ''They Got Us Right Where They Want Us, At Each Other's Throats''.
