He left his mark on rock & roll, and now a tribute to Ronnie James Dio is on the way. Black Country Communion vocalist Glenn Hughes says he and several other hard rock notables have committed to the project. In an interview with Bravewords.com, Hughes said Queensryche's Geoff Tate, Rob Halford of Judas Priest, and Iron Maiden's Bruce Dickinson will get together to record some of Ronnie's material for the tribute album. Hughes went on to say that Dave Grohl and Zakk Wylde will play on some tracks, and that he and Dio's widow Wendy want people who knew Ronnie to be a part of the project, and Ozzy Osbourne may also appear.
