Zach Shaw: Within Temptation’s Founding Guitarist Retires From Touring. www.metalinsider.net. [dostęp 2017-01-02]. Cytat: "To be able to fulfill the needs of our children but just as much the needs of the band for now and also in the future, we decided Robert will step down from touring live, (except for the occasional show). With this change we can give stability to our children and from the home studio Robert will have more time writing new music and developing new creative ideas for the live show, the comic and future movies."
