Elmo Kennedy O'Connor was born in Muir Beach, California to a mother who designed clothing and a father who was a photographer.

"[8] O'Connor describes Howell as a "mundane" place where its residents are "born and they die there",[8][6] also calling it "one of the most racist towns in Michigan".

He would download hip hop instrumentals from SoundClick and use the computer's built-in microphone to record himself rapping, though it wasn't until 2010 at the age of 16 that he would start releasing music online under the alias "Th@ Kid", often on MySpace or other early internet blogging services.

After moving to Los Angeles, O'Connor connected with other artists he met online including Xavier Wulf, Chris Travis, and Eddy Baker, who at the time were members of the now semi-disbanded Raider Klan.

O'Connor uploaded several albums in 2015[17][18][19][20] and headlined his first sold-out show at House of Blues on March 4, 2015[21][22] before opening for electronic artist Shlohmo at The Fonda Theatre.

O'Connor is a founding member of the collective Seshollowaterboyz, along with Xavier Wulf, Chris Travis and Eddy Baker, with whom he often performs and collaborates.

They have performed at notable venues such as The Observatory in Santa Ana, California on November 13, 2015 [31] and The Novo by Microsoft in Los Angeles on January 30, 2016.

[32] After Chris Travis left the group in 2019, the remaining members would continue touring under "Bones with Eddy Baker and Xavier Wulf."

On March 12, 2024, after Wulf's former girlfriend of 5 years took to Reddit to accuse him of sexual assault, animal abuse and domestic violence, he was promptly kicked out of the group and off of Limp Bizkit's Loserville Tour.

[33] As of July 5th, 2024, BONES and Xavier Wulf have reunited and have performed together at a Robb Bank$ show in downtown Los Angeles and he has been added back to the Loserville Tour.
