"The hologram of the late Ronnie James Dio will tour this year with singers with Ripper Owens and Oni Logan. 

The hologram debuted on August 6, 2016 with a surprise appearance before 75,000-plus fans at the Wacken Open Air music festival in Germany. Dio, who died in 2010 at age 67, was shown belting out “We Rock,” the late singer’s go-to encore song, with Dio Disciples, a band made up of several of his former bandmates.  

Created by Eyellusion, the Dio hologram is the world’s first rock hologram performance and its Wacker Open Air performance marked the first time a hologram had been accompanied by a live band onstage. "
