“READY FOR WAR” was first shown on Kevin Abstract’s Instagram Live video, one of the first social media appearances from any members of the band in around a month.

The song was teased just days before Ameer Vann’s removal from BROCKHAMPTON.

The violin instrumental from this song was later used in an unnamed song debuted during the third episode of BROCKHAMPTON’s Things We Lost In The Fire radio. The song was supposed to appear on PUPPY, which was scrapped.

The visual for the song was shown in BROCKHAMPTON’s The Longest Summer In America documentary and was leaked to YouTube on May 27th, 2019.

The mastered version of the song leaked in April 2024 to YouTube and other platforms, along with a separate version featuring background vocals and a verse from R&B icon Mary J Blige.
