"1999 Wildfire" was originally created during the sessions for Brockhampton's planned fourth studio album
Puppy. At the time, the track was set to be the second song on the album, and originally went by the name "Big Fat Liar". Leaked demo versions of the track showed a pitched-up verse from then-member
Ameer Vann, a full verse and additional backing vocals from Jazze Pha, and alternate vocal takes on Dom McLennon and
Matt Champion's verses. After
Puppy was scrapped due to the removal of Vann, the song was then likely slated to be released as a part of a new album titled "The Best Years Of Our Lives"; this album was also eventually scrapped. The song premiered on Brockhampton's
Beats 1 radio show
Things We Lost in the Fire Radio, in the first episode. It was followed by a video shortly after. When Brockhampton's fourth studio album,
Iridescence, did finally release in September 2018, the track did not make the final cut of the album. ==Composition==
