Now Playing. Dio - Holy Diver. One of the best metal albums ever and certainly Dio’s crowning achievement. This LP is loaded with pure heavy metal. I love the drumming of Vinny Appice and Dio’s soaring vocals. The unsung hero is Vivian Campbell. His guitar work is awesome. Incredibly crunchy riffs and fast leads take this album to another level. I played the title song so many times as a kid. I’ve always found Dio’s lyrics highly relatable. Every tune rocks and Dio had a gift for melodic singing in a metal context. ”Holy Diver” ranks high for me on the list of best metal albums.
