jazz from hell
Ancient Mariner
Dio was very bluesy sometimes (e.g. Mistreated). Bruce more emotional? I don’t know.But he's nowhere near as emotional as Bruce. It's easy to sound great when you stand rooted to the spot singing every song with the same voice without trying to show your emotions - that's what I personally never liked about Dio, though his voice is very strong, but opera singers for instance have much more powerful voices, but the same lack of emotions is a big minus.
But Gillan, Bruce and Dio would be the real Trinity Of Souls imo.
