Ronnie James Dio Hologram Concert Tour After debuting at last year's Wacken Festival in Germany, a hologram of late heavy-metal singer Ronnie James Dio set out on a world tour, backed by musicians who played with him, last fall. The trek, dubbed "Dio Returns," kicked off with a European leg of performances in theaters on November 30th in Helsinki before hitting South America, Australia and Asia. The tour will arrive in the U.S. in the spring of 2018 and hit select festivals next summer. The Dio Band consists of guitarist Craig Goldy, drummer Simon Wright, keyboardist Scott Warren and bassist Bjorn Englen. The musicians have previously made appearances as the Dio Disciples.
