Supercalifragile is the sixth and final studio album by Game Theory, a California power pop band founded in 1982 by guitarist and singer-songwriter Scott Miller.

He received significant critical acclaim for albums such as Game Theory's Real Nighttime (1985) and Lolita Nation (1987), achieving cult status but little commercial success.

[9] The source material for the songs included "a handful of studio recordings that could be finished without too much trouble, [and] some acoustic demos that it would be possible to track instruments along to and make them album quality".

[9] Game Theory's former producer Mitch Easter, without a co-writing credit, contributed guitar, drums, synth, and mixing to complete Miller's song "Laurel Canyon".

[9][7] In the summer of 2015, recording took place at Abbey Road Studios in London for the song "I Still Dream of Getting Back to Paris", co-written by Miller, Schück, and Barbeau.

[5] Game Theory members Nan Becker, Dave Gill, Gil Ray, and Suzi Ziegler participated in recording sessions in late May and early June 2016, held at Sharkbite Studio in Oakland, California.

[13] Additional members of Game Theory who appeared on the album included Donnette Thayer, Fred Juhos, Shelley LaFreniere, and The Loud Family's Alison Faith Levy.

Fluxblog's Matthew Perpetua pointed to the album title's play on the Mary Poppins song "Supercalifragilisticexpialidocious" as "a perfect example of Scott Miller's wit as a lyricist – a mawkish bit of Disney nostalgia broken in half to reveal a vulnerability that was always right there in front of us.

[18] GIGsoup reviewer Ian Rushbury described the album as "a quiet triumph for all concerned... better than even the most die-hard fan could have hoped for", writing that it "sits perfectly in Miller’s enviable catalogue" as "a fitting epitaph to a body of work like none other.

Directed by Hector Di Napoli and shot during recording sessions at Abbey Road Studios, the release previewed the final album version with a rough preliminary mix of the audio.
