Despite being relatively inactive since 2007, all members have stayed in contact, and have independently shown interest in working on a second album if the logistics and scheduling of their commitments to other bands ever aligned.
Shortly after releasing Filter's third album, The Amalgamut, Patrick checked himself into rehab in October 2002, ceasing all band activity and touring for the time being.
[2] Around the same time, in late 2002, Stone Temple Pilots broke up due to increasing problems with lead singer Scott Weiland and his issues with substance abuse.
[6] Patrick felt so strongly about the music that he put the fourth Filter album on hold, despite his record label urging him to continue, in order to start a new band with the DeLeo brothers.
[10] Beyond the label switching, Patrick commented further delay was caused by personal commitments, such as members' families getting married and having children.
[10] They were able to fit this into their schedules because they used Andrew's Pro Tools set-up at his house, rather than renting time at a high-budget studio.
The band's first single was the track "Goodbye", which gathered significant radio airplay, peaking at number 3 place in the U.S.
[11] The band started touring in support of the album on November 18, including performances of "Goodbye" on Late Night with Conan O'Brien and Last Call with Carson Daly.
[18][19] Later in the year, Patrick confirmed that he had returned to working on the fourth Filter album,[20] and publicly announced that Army of Anyone was on hiatus.
Robert and Dean DeLeo rejoined Stone Temple Pilots when the band reunited in early 2008 to play a reunion tour[17] and then released their self-titled sixth studio album in 2010.
[23] However, no other band members would report on such concrete plans, with Patrick even stating in a July 2010 that Filter was his main focus for the foreseeable future.
In a November 2011 interview, Patrick said of the future of the band: Those guys are amazing, it's basically this simple: Robert has a studio in his basement where he can totally do his old-fashioned kind of classic sound.
[26]When asked in May 2012 about the future status of Army of Anyone, Luzier reiterated Patrick's comments that they were still in contact, and even stated there was music they were working on, responding, "It's possible.
[29] However, in regard to working on new music as a band, Patrick referred to it as "a sleeping beauty" that " won't wake up for a long time to come".
