In 2005 Jacob was one of three new players to participate in the Swedish/German hard rock band Last Autumn's Dream for its second studio album, along with drummer Jamie Borger and keyboarder Thomas Lassar. They were hired to replace John Levén, Ian Haugland and Mic Michaeli, who played on the debut album, but who could not make it this time due to taking part in the Europe reunion. Jacob also recorded Last Autumn's Dream five further studio albums, the latest being "Dreamcatcher", which was released on 26 January 2009.
