No release date, method, or further details have yet been announced, though the record does, in fact, appear to be a full-length.
Check out announcements from both Farro's personal and HalfNoise accounts:
Finished tracking the @HalfNoiseMusic album. Can't wait for you all to hear it! New Zealand thank you for everything.— Zac Farro (@zacfarro) September 29, 2013
Zac documented much of the unique recording process, with photos and video clips, via Instagram. The performer has, so far, released one EP as HalfNoise: last year's self-titled debut, on which he serves as singer, arranger, and multi-instrumentalist.
