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"

Farro and Clark had earlier been together in a band with Taylor York and Zac Farro's brother Josh Farro prior to Paramore. The duo then renamed themselves "HalfNoise" due to other bands being named "Tunnel". In March 2011, it was announced that Farro would be joining his brother's band Novel American, but would still continue take part in HalfNoise.

After left Paramore, Zac Farro started working in Half Noise's debut EP self titled HalfNoise. The EP production was finished on 2011, according with Farro to NME. Farro also stated to NME that he recorded almost all the instruments with his friend Daniel James, "I played all the drums, I did all the sampling. Me and a producer called Daniel James did the guitars together, but it was mainly just me performing." On June 14, 2012, Half Noise released "Free the House" their first official song and music video from the EP. HalfNoise was released on October 01, 2012 on the UK through Xtra Mile Recordings and October 02 through their official website. The EP composed of previous demos from 2010 and new material.
