PITTSBURGH — Back in 2014, when he was issuing the mixtape "Faces," Mac Miller was also working on a full-length album that was never released.

On Jan. 17, "Balloonerism" will see the light of day, along with an accompanying film directed by Samuel Mason.

"It is a project that was of great importance to Malcolm — to the extent that he commissioned artwork for it and discussions concerning when it should be released were had regularly, though ultimately 'GO:OD AM' and subsequent albums ended up taking precedence," the late Pittsburgh rapper's estate noted in a statement.

"We believe the project showcases both the breadth of his musical talents and fearlessness as an artist. Given that unofficial versions of the album have circulated online for years and that releasing 'Balloonerism' was something that Malcolm frequently expressed being important to him, we felt it most appropriate to present an official version of the project to the world."

"Balloonerism" would have fit in the discography between 2013's "Watching Movies with Sound Off" and 2015's "GOOD:AM."

It will be available digitally as well as a variety of physical formats including CD, cassette and vinyl. Vinyl will be available as a two-LP release across two exclusive variants only available through balloonerism.com — a one-time, limited edition deluxe pressing that features a rainbow foil-wrapped slipcase with white splatter cloud vinyl and a 32-page color booklet featuring photos and lyrics as well as a limited one-time pressing that features clear vinyl.
