In 2000, Marx debuted his sixth studio album Days in Avalon. This disc was released on the Signal 21 Records label founded by Marx and former Blood, Sweat & Tears drummer and record producer Bobby Colomby. Its title track, "Days in Avalon", was picked up by Adult Contemporary radio and spent 12 weeks in the chart's Top 30. The album was also quite successful in other parts of the world, particularly Asia and Australia. The label became the vehicle for the release of this disc, and folded shortly thereafter.
