Although Ronnie James Dio is sadly no longer with us after losing his battle with cancer in 2010, the greatest voice in heavy metal history lives on! The Dio Returns Tour has just been announced! You can see the trailer for the trek below. While the visual part of the tour will be made possible using hologram technology provided by Eyellusion, our ear holes will be caressed by vocals pulled from past live Dio performances. Joining Holo-Dio on stage will be guitarist Craig Goldy, drummer Simon Wright, keyboardist Scott Warren and guitarist Bjorn Englen. Tim “Ripper” Owens and Oni Logan will also be on hand lending their considerable vocal talents to the mix. The “Dio Returns Tour” is said to kick off on June 1st.
