Ativin was founded in late 1994 by Indiana University students Chris Carothers (guitar) and Rory Leitch (drums). The group became a trio the following spring with the addition of guitarist Dan Burton. This lineup recorded the band's debut EP, Pills vs. Planes, which was released in December 1996.
In 1997, Ativin released the "Modern Gang Reader" / "Larkin" single via Secretly Canadian. Their debut LP, German Water, followed in March 1999. Jonathan Cohen from AllMusic praised the band's compositional skills and described their sound as possessing an "intelligent heaviness."
Following a tour in support of the album, Ativin disbanded. Dan Burton subsequently formed a new group, Early Day Miners.
In 2001, Ativin returned with a new drummer, Kevin Duneman, and released their second studio album, Interiors, in 2002. Jason Nickey from Pitchfork observed that the band's sound had changed significantly following the reunion. Nickey criticized Duneman's drumming for "lacking the punch and quick snaps" of former drummer Rory Leitch. Additionally, he compared Burton's guitar work to that of Early Day Miners, suggesting that Interiors felt more like an Early Day Miners release.
