At times her voice still has a feminine touch. Much like Angela from Arch Enemy does.
One of my best friends is like 120 pounds, 5'4" ish, and she could do all the vocals to Job for a Cowboy's "Entombment of a Machine." Was brutal. I can assure you she's female though, she's havin a kid next month.
That being said, I like the production. Vox are a bit loud for my taste, but that's just a personal preference. Either way it's years beyond anything I've done.
