His first album The Nebulizer was released on 14 October 2011. The album was produced by Nebs, hence the name. According to an article in INpress, “Kerser is raw, aggressive and territorial,” while the album is “A fervent mix of rave, rap, electro and r’n’b.” He gained fame from the track “Kerser is the sickest” that was also on the first album.

His second album No Rest for the Sickest was released on 2 November 2012. It reached No. 15 on the ARIA Albums Chart, and No. 1 on the ARIA Urban Albums Chart. He toured nationally to support the album.
