Justin Mauriello started I Hate Kate in 2004, while still in Zebrahead, as a creative outlet. The band has seen a steady rise in success. I Hate Kate played with bands such as Social Distortion, Chevelle, Hot Hot Heat, The Bravery, The Living End, My Chemical Romance, Unwritten Law, Secondhand Serenade, and Shiny Toy Guns. Tours have taken them throughout the U.S., Canada, and Japan.
December 2007, the band took to the studio with platinum producer Mark Trombino (Jimmy Eat World, blink-182, Sugarcult), recorded new songs and remixed previous tracks.
