Diggin "Rise to the Call." Nice Priest vibe with the riff. Love how the tune ratchets up at the end. Great note by Michael Sweet.
About them tuning down live - I don't blame them. When I saw them do the To Hell With the Devil anniversary tour, they did everything in the original key. The set of modern songs and other tunes was great. But once they played THWTD, Michael struggled. It was a bit of a bummer.
That said - I saw some footage, I think from Puerto Rico a week ago, where it sounded like they were tuned down, and the songs lost a lot of their dynamics and punch. Personally, I like the stuff from the 80s going down a half-step, but for some songs, it doesn't work well at all (A lot of Tesla's stuff sounds bad tuned down). Back when Tate was in Queensryche and they were down a half-step, it actually sounded a little better. It really depends on the band. I'm hoping Stryper takes a hard look at things, and keeps old songs where it works well, and just cuts songs (even if classics) where it doesn't.
Stryper's music over the last 15 years has been killer. Personally, at this point, other than a handful of old tunes, I'd love to hear them just do modern material.
