Fates Waring - any of their material from 1997 to present.
Orphaned Land - Either of their last two albums. Mix of prog/rock/metal and middle eastern music.
Everygrey - a bit more metal than the rest, but with prog influences and clean vocals (no growly stuff).
You may want to check out The Joy Formidable. They are more pop than any of the other bands mentioned, but the certainly have the peaks and valleys, particularly on their first album. And they are amazing live.
Thank you for the suggestions, I'll try them out. Are you a fan of Karnivool & Dead Letter Circus? I love them personally, Karnivool's latest album isn't one of their best, but after a few listens you appreciate it much more.
