Joey Walker

Walker was born in Northern Australia and raised in the town of Kununurra, where he got into local indigenous rock bands such as Yothu Yindi[3] and Warumpi Band when first getting into music.[4] He would see both of these acts perform at the Stompen Ground festival of 1992. He would later discover progressive acts such as Tool as a teenager, leading him to earlier progressive rock bands such as Yes.[4] Walker would eventually move to Melbourne.

While in high school, Walker would meet Alex Braithwaite who moved to Melbourne from England. Braithwaite would introduce Walker to UK Drum and bass, inspiring the two to make their own electronic music using a set of turntables Braithwaite had also brought.[5] The pair would call themselves Trumpdisco, and began to release music while both in university. They saw quick success with their first track, "Supermassive", a remix of "Supermassive Black Hole" by Muse. The duo would see international airplay on radio and in clubs and were even able to do shows internationally starting with a date in New Zealand in 2009. Walker would continue working with Trumpdisco for a number of years, beginning to be less involved around 2013[6] following the success of King Gizzard before fully leaving the duo around 2016. Alex Braithwaite would turn Trumpdisco into a solo project, renaming it to SUB-human.

Walker attended the Royal Melbourne Institute of Technology at which he would study for a Bachelor of Arts degree in the music industry.[7] It was in this class where Walker would first meet Stu Mackenzie and Eric Moore.[8] In 2010, the three of them would form an informal "jam band" which was to become King Gizzard & the Lizard Wizard. Over the course of a few months, they would recruit several more members who were mutual friends of the trio. Walker and the rest of the band would make much of their work in the class focused around King Gizzard. King Gizzard would rapidly grow in popularity following the release of their 2nd EP, Willoughby's Beach in 2011 and debut album, 12 Bar Bruise in 2012 on their own independent label Flightless Records.

Walker had a long lasting interest in electronic music, previously creating some electronic works for assessments in college[7] and being half of the electronic duo Trumpdisco. Walker would release his first solo electronic project in 2014 via SoundCloud, a track titled "Expectant 2".[9] In 2017, Walker began recording solo as Bullant, beginning work on an album in the coming months.[10]

On 13 August 2019, King Gizzard would release a game on their website to promote their upcoming album, Infest the Rats' Nest.[11] Hidden within the game was an easter egg teasing the upcoming album, Tyson, Crying, the debut album by Walker as Bullant. On 4 December 2019, Bullant released his debut single in support of the upcoming album, "The Simpsons Suck Now" under Flightless Records. Another single for the album, "XHamster Invoice" was released on 24 January 2020.

Bullant's debut album, Tyson, Crying, would be released on 31 January 2020. The album was recorded by Walker in 2018 using "a demo version of Reason and an Ableton crack", stating in a press release "I couldn't save any sessions out which forced me to finish each track on the spot."[2] Matija Zivkovic of X-Press Magazine would give the album a 7/10, stating "Overall, this isn't an essential release but it's also highly listenable, eclectic and fun. With a slightly more pared-back approach and a non-cracked version of Ableton, Bullant could prove a great electronic diversion from the largely guitar-driven Flightless Records stable."[12] Cole Costello of Cosmic Magazine would say "Given his contributions to Gizzard, one might have expected heartfelt lyrics, blazing guitar lines, and magical melodies. Perhaps he's simply saving that kind of material for King Gizzard – a group which, with exception of more left of center excursions like these – his commitment remains total... But whether this kind of music is something fans will see more or none of in future, Joey Walker has already proven himself a musician. Tyson, Crying is trying to show the listener something else to fans, something other than what they already know. What that is may is not up all listeners' alleys, though certain it adds another layer of complexity to Walker's persona."[13]

On 2 July 2020, Bullant would release an EP under PHC Films rather than Flightless called German People featuring artwork by Amy Taylor of Amyl and the Sniffers.[14] It would be followed up on 10 July by another EP titled Sensitive Crap Opera[15] Bullant's final release of 2020 was a single put out on 16 July titled "Irukandji".[16] On 30 July 2021, Bullant would return to release the single "High Rivals".[17]

In December 2021, King Gizzard announced Butterfly 3001, a remix album of songs from the band's 2021 release Butterfly 3000. Bullant would contribute a remix of the song "2.02 Killer Year" to the project, titled "2.02 Killer Year (Bullant's Fuck Mike Love Remix)".[18] The album was released on 21 January 2022.

On 18 January 2023, the PHC Films Instagram account announced an upcoming release from Bullant coming in February 2023.[19] On 17 February 2023, the single "Rove" would be released under PHC Films with the b-side "Trade". This was followed up by an EP on 10 March titled U Wunda and a single on 7 April titled "3AW" with the b-side "James Shares A Needle".

On 19 July 2023, Bullant announced his upcoming album, Late Life Circ, with a release date of 1 September.[20] Pre-orders would open the next day alongside the release of the album's first single, "Perfect shelving technique",[21] this would be followed by a second single on 3 August titled "Clown From Two Towns Over",[22] both singles featured artwork by Amy Taylor.

Walker currently resides in Reservoir, Victoria.[23] It was from his home in Reservoir where many of his parts for King Gizzard albums K.G., L.W., and Butterfly 3000 were recorded.

Walker's sister, Bella Walker, plays in the band The Bush.[24] Bella Walker has also provided backing vocals on King Gizzard's 2020 track "Minimum Brain Size" and has done color grading on several videos by King Gizzard and The Murlocs.

Walker is in a relationship with Edith Kenny-Smith, former bassist for The Bush and the sister of King Gizzard bandmate Ambrose Kenny-Smith.[25]
