AND BLOOD TEARS I CRY
ENDLESS GRIEF REMAINED INSIDE
CUT OFF YOUR OLD FRIEND'S HAND
all the old albums are good/great in some kind of way, but a Twist is basically crap.You hit it spot on, I'd say. A Night At the Opera was a really good record, but A Twist in the Myth had nothing special about it. A few decent songs (that sounded like they could have come from Nightfall in Middle-earth or A Night At the Opera), but nothing remarkable.
I'd say they're more power with thrash elements from what I've heard.I dont really consider Blind guardian power metal, they started out as a speed metal band, and just went thrashy majestic really.
