I agree with you there. Killswitch does have fantastic stage presence. Would love to see them again one day.
Until I met my husband, I was into mellow stuff. Anberlin was and still is my absolute favourite, they're not any kind of metal, but there's something about them I love. If you want stage presence, they put on a wicked show. My husband, who is HUGE into any kind of metal (has over 3 months worth of music on his iTunes), even enjoys a few of their songs and loves their shows...but don't tell him I told you that.
Among other favourites he's gotten me into:
He Is Legend
From a Second Story Window (RIP) (Named our daughter after their 2006 album)
Mellow...but amazing, Further Seems Forever...also RIP, just listen to the drums
The Breather Process
I could go on forever.
