Jackson Mendoza's debut single, "Venus or Mars", was the first song penned by music production team, the Matrix. "Venus or Mars" was released in October 1999, spent ten weeks on the top 50 of the ARIA Singles Chart, which peaked at No. 24. It reached No. 31 in New Zealand. Their follow-up single, "Ordinary Girl" (August 2000), also reached No. 24 in Australia but did not peak in the top 50 in New Zealand. The group disbanded soon after with both members pursuing acting careers.
