I'd heard of April Wine as a kid, but don't think I ever actually heard them. I only know "Between You And Me", and that's only because it pops up on the VJ Big 40 once in a while. And I only learned of Prism over the past few years thanks to the VJ playing their top 40 hit Don't Let Him Know. Never had heard of Trooper.
Armageddon is good. Definitely has that turn-of-the-decade-rock sound that I don't normally get into, but I definitely do dig this one. If I can try to be a lil funny-yet-honest, the chorus bass line sounds like something from a Donkey Kong/Mario video game though. And if I can be curious, I wonder what the line "Ain't got time to lose U-boats off New England" is about? Me, being a New Englandah an all.
