Cardinal Sin is a death/black metal band formed by John Zwetsloot when he left Dissection in 1994. In 1996, they released a 4-track EP called Spiteful Intents, which featured a trademark classical composition by Zwetsloot. Having disbanded after the EP, they reformed in 2003 with a partially-new lineup, but have yet to release anything beyond "Spiteful Intents."
