Former Dio/current Dio Disciples drummer Simon Wright says there's a chance that four unfinished demos could be completed for a future release.

"There were three or four songs he had been working on," says the drummer. "I'm not sure what will happen. At some point, maybe, they'll come out. You would have to be careful how you approached it – you wouldn't want to overstep your bounds. We'd sit and listen to them and see how far he got. We'd do it with total respect and we'd do it delicately."

Ronnie James Dio's last track, Electra, was released after his death, but it’s actually a prelude to the records that Ronnie was working on which would have been Magica 2 & 3. That’s the special bonus on the record. There’s also the track Metal Will Never Die which is a track that Ronnie recorded with ‘Rock’ Feinstein, his cousin from the band The Rods. That was the last song that Ronnie ever sang on. There’s also the song Prisoner in Paradise which is a bonus track to the Japanese edition of Master of the Moon— which is a very difficult song to find.
