Webster was originally of the band Beyond Death, with ex-Cannibal Corpse guitarist Jack Owen, back in 1987. Both met up with Chris Barnes, Bob Rusay and Paul Mazurkiewicz, all of whom were in the band Tirant Sin. He was the one to come up with the band's name, Cannibal Corpse. In an interview he said that he thought it was a very catchy name for a band. He has a reputation for being friendly to his fans, often asking questions, and genuinely caring what his fans think, regularly answering questions on the band's forum. Alex also recorded bass for Hate Eternal, Erik Rutan's death metal band. Erik is the producer for Cannibal Corpse's albums that were released between 2006 and 2012, Kill, Evisceration Plague, and Torture. In 2005, Alex was contacted by guitarist Ron Jarzombek about a possible collaboration which became Blotted Science, an all-instrumental extreme metal project. They released their debut album, The Machinations of Dementia, in the fall of 2007.
