Prior to the formation of Paramore, drummer Zac Farro was in a band along with guitarist and childhood friend Jason Clark, current Paramore guitarist Taylor York and Zac's older brother Josh. Two days after leaving Paramore at the end of 2010 along with Josh, Zac reunited with Clark when they formed Half Noise. Speaking with NME in September 2012, Farro revealed that became the sole member of HalfNoise after Clarke departed the project earlier in the year. He added that Clarke, along with producer Daniel James, had been crucial in the creation of their debut record, HalfNoise EP. "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," he said. There are trumpet, French horn and glockenspiel samples too. I write in the mind of a film score, that's really the dream, what I'd like to be doing soon."
Farro has described the band's sound as, "combining the ambience of bands from Iceland with the sampling and electronic elements of Radiohead."
