[3] ZP Theart was born on 27 May 1974 in Clanwilliam, Western Cape, South Africa, and he grew up in Hazyview in the Eastern Transvaal (now the Mpumalanga province) on a banana and lychee farm.

He has stated that according to his mother, at the age of three years, he began to hold a tablespoon up to his mouth, pretending that it was a microphone, and singing to whatever was on the radio.

He has stated that in his early childhood, he listened to South African artists such as Gé Korsten, Carika Keuzenkamp, and Rina Hugo, but his older brother introduced him to other music cassette tapes that he had brought home from high school, some of them being A-ha, Alphaville, Sandra, and Depeche Mode.

In mid 1999, Theart began to put out advertisements across studios in London, which were eventually responded to by Demoniac guitarists Herman Li and Sam Totman.

In early 2010, Valley of the Damned and Sonic Firestorm were re-released with bonus DVDs, featuring live footage, interviews, and other things.

[7][9] Theart served as the touring vocalist for the heavy metal band Tank in 2013, becoming an official member the following year.

His only studio album with the band was Valley of Tears in 2015, being replaced with David Readman shortly after due to his transition into Skid Row.

On 13 September 2024, Theart collaborated with original Iron Maiden vocalist Paul Di'Anno for a new version of the song "Wrathchild" featured on The Book of the Beast.
