Delain was founded by Martijn Westerholt and Charlotte Wessels. Westerholt is the ex-keyboardist and brother of one of the founders of Within Temptation, Robert Westerholt. He left Within Temptation in 2001 when he suffered from Pfeiffer's disease. Wessels was, at that time, an unknown singer living near Westerholt. They started Delain, as a project involving many of Westerholt's friends in the Symphonic Metal Community, in 2002, and began recording the debut album in July 2005, after they had signed a contract with Roadrunner Records. They've released three albums: Lucidity, April Rain and We Are The Others.
