King Gizzard & Lizard Wizard - Polygondwanaland - Picture Disc Vinyl

is the twelfth studio album by Australian psychedelic rock band King Gizzard & the Lizard Wizard. The album was released under an open source licence—the band uploaded the master tapes online for anyone to use. It was released on 17 November 2017. It was the fourth of five albums released by the band in 2017.^[1]

The album's title is a portmanteau of the words polygon and Gondwanaland.

Polygondwanaland first appeared as a partial leak on the band's demos for the album. The leak was uploaded to SoundCloud, but was soon taken down. As a result, news of the album was scarce and mostly involved rumors, one of which stated that it would be the last of the five albums released in 2017.^{[citation needed]}

The track "Crumbling Castle," which appeared on the demo, was performed live by the band as early as September 2016, albeit in a much shorter form.^[2] However, it lay dormant for many months during an especially prolific period for the band, leading to speculation that the track might have been scrapped. Both the track and the music video were finally released on 18 October 2017, exactly one year after the first performance of the song was uploaded to YouTube.^[3] The legitimacy of the demos were all but confirmed at this point, as not only did the track feature the album's name in the lyrics, but it also contained lengthy musical passages equal in duration to the demo.
