I don’t know how you can be a “massive metalhead” and never heard of Dokken. Anyway, guys/bands like this are what I refer to as Political Cicadas. They run on 4 or 8-year cycles. When a republican assumes the White House they spring forth from their slumber and attempt to recapture their own little slice of relevance for a reunion tour or project launch. Like their insect counterpart, they’ll disappear again soon enough.
The 80s was a little before my time as far as music. My older brother listened to Crue, Pantera, Metallica, and a bunch of others and being exposed to it when I was real little, I grew up listening to it and still do. Never heard of dokken until today so they must be highly forgettable
