In March of 2018, King Gizzard played an untitled instrumental two times. The song, intended to be recorded for an unknown, then-upcoming album, heavily resembled the AC/DC track “Riff Raff” from their 1978 album Powerage. Since its disappearance, the song remains a curiosity in the band’s catalog with no releases and little info offered by the band. It’s the only taste of a project for which there is little info, but speculation could lead us to infer that it may have become Infest the Rat’s Nest.
The first known performance was on 2018-03-06 at the Paradiso Grote Zaal in Amsterdam. Stu introduced the song by saying this: “We’re gonna try something here… we’re recording this tonight. We’re recording this. We’re gonna try something now. This is kinda new. It’s got no words yet. We’re gonna record it and work some other shit out later but… unintelligible I’m scared.” It was played one more time on 2018-03-11 at the Neue Theaterfabrik in Munich. Before playing the track, Stu once again mentioned that the band were recording the performance. In the years following, however, the band never gave an explanation as to what this was. This led some to theorize that it was cut due to its similarities to the AC/DC song “Riff Raff,” which the band began to use as intro music later that year. However when asked if the song would ever see the light of day during King Gizzard’s 2020 Reddit AMA, Stu said “forgot about this one! might have to resurrect it from the dead…”
