In the 2020s, the band released two further microtonal studio albums – K.G. The 2019 albums Fishing for Fishies and Infest the Rats' Nest saw the band tackle environmental themes and incorporate boogie rock and thrash metal, respectively, into their sound. In 2017, the band fulfilled a promise to release five studio albums within the year: Flying Microtonal Banana, an experiment in microtonality, in February the three-chapter "sci-fi heavy metal epic" Murder of the Universe in June Sketches of Brunswick East, an improvised jazz collaboration with Mild High Club, in August Polygondwanaland, which was released into the public domain in November and Gumboot Soup in December. Nonagon Infinity features nine interconnected tracks that form an infinite loop and won the ARIA Award for Best Hard Rock or Heavy Metal Album. In 2015, they drew on elements of jazz fusion and progressive rock with Quarters!, and also released the folk-inspired Paper Mâché Dream Balloon, recorded almost entirely using acoustic instruments. Float Along – Fill Your Lungs, released later in the year, and the 2014 albums Oddments and I'm in Your Mind Fuzz, saw the band expand on their psychedelic sound.

Their second album, a "psychedelic spaghetti western" titled Eyes Like the Sky, features spoken-word narration by Broderick Smith. Their second EP, Willoughby's Beach, and debut album, 12 Bar Bruise, primarily blended surf music and garage rock, and were released on Flightless, the band's own label. They are known for exploring multiple genres, staging energetic live shows and building a prolific discography, having released 23 studio albums, 14 live albums, three compilations and three EPs.

The band's current lineup consists of Stu Mackenzie, Ambrose Kenny-Smith, Cook Craig, Joey Walker, Lucas Harwood and Michael Cavanagh. King Gizzard & the Lizard Wizard are an Australian rock band formed in 2010 in Melbourne, Victoria.
