The band members are advocates of the DIY punk ethic, as popularized by bands such as Fugazi and The Minutemen. Replicator started as a bay area Indie rock band of little distinction before finding their signature sound, often compared to bands such as Shellac, The Jesus Lizard, Steel Pole Bathtub and The Melvins.
Straddling the fine line between "social commentary and smart ass revelry" as well as "technical precision and reckless abandon," Replicator used analog tape deck to play samples live until switching to a laptop computer with the Bludgeonsoft software Back to Basics for sampling.
The band recorded their first record Winterval with Bob Weston of the band Shellac, triggering understandable comparisons to that band that would hound Replicator for years to come. Shortly afterwards, bass player Dan Kennedy left the band. The lineup solidified in 2001 when Indiana expatriate Ben Adrian
joined the band on bass guitar. Adrian often joked that he was still "filling in" on bass 6 years later. 2002 and 2003 saw the band tinker with sound effects, taking the sampling (or "grand theft audio" as Neutron put it) practices of Steel Pole Bathtub and adding this to their developing aggressive and chaotic sound, as well as keyboard.
This sound was represented in the album You Are Under Surveillance. Frequently cited
, as chaotic, dense and paranoid, Surveillance was apparently a loose concept album based upon the ideas of "paranoia, lost freedom of choice, airborne revenge, the end of the world, the problems and consequences of an overgrown consumerist, bottom line-oriented culture; and the merits of applied righteous indignation" 
In September 2004 on one of their "ReplicaTours"
, Replicator's van was broken into and their guitars and keyboards were stolen Luckily they were able to borrow the equipment of their tourmates Greenlight the Bombers and continue. This theft occurred during the 2004 rash of equipment thefts that plagued many working musicians.
2007's Machines Will Always Let You Down, seems to also be a loosely based concept album, this time around the conflict between man and machine. The press materials state that it is: 10 songs about Nanotechnological assassination, time travel, building sex robots, the eternal battle of man vs. machine and other things.

This record was recorded by Vern Rumsey of the band Unwound and was released on Olympia's Radio Is Down record label.
2008 also saw several more US Tours, including a full us tour documented in a tour journal on the music website superstarcastic.com
On January 2 (2008), an announcement
was made on the Replicator website that "After 8 years, 3 albums, 2 eps, 4 vans, almost 200 shows, a handful of compilation appearances, and countless floors" the band had agreed to an amicable mutual break up. After recording a final ep
, (Including a cover of Babyland's Arthuer Jermyn), released again on Radio Is Down, Replicator played their last show at The Hemlock Tavern in San Francisco on April 5th (2008).
, Neutron himself was under surveillance at the time for his activities as head of Bands Against Bush. Said Neutron in response: "I'd hate to think what they would have done if we were doing something more nefarious then putting on shows and registering voters." 
have questioned if it is a case of simultaneous inspiration or indeed a case of (unlikely) musical plagiarism, Replicator has thus far laughed this off.
, the song titles almost always are inspired by or inspire the lyrical content of the songs, unlike other contemporary bands with similar song titling such as Don Caballero (who do not have vocals) and Minus the Bear.
