Halfnoise was created two days after Zac Farro's departure from Paramore, under the original name "Tunnel". Zac took part in this new project, along with Jason Clark, releasing a new song called "Hide Your Eyes" and later on released "Free the House" There First Official Song and Music Video. The duo then renamed themselves "Halfnoise" due to other bands being named "Tunnel". Farro and Clark had earlier been together in a band with Taylor York and Zac's brother Josh Farro prior to Paramore.



In March 2011, it was announced that Zac Farro would be joining his brother's band Novel American, but would still continue take part in Halfnoise.





Zac has stated that some of his influences include: Jimmy Eat World, Radiohead, Death Cab for Cutie, Mew, Paper Route, Sigur Ros, Thrice, Sunny Day Real Estate and múm. Farro has been influenced by Dave Grohl (former drummer of Nirvana and current singer/songwriter of Foo Fighters and drummer for Them Crooked Vultures), William Goldsmith (former drummer of Sunny Day Real Estate and Foo Fighters, replaced by Taylor Hawkins) and Riley Breckenridge (drummer for the band, Thrice).
