What!!!?? Growls again?? I haven't even had the opportunity to listen to that first track yet but I didn's see that coming. I wouldn't say I needed them but I don't mind having them back either. I love death metal Opeth at least as much as prog rock Opeth, and extreme metal vocals have never been a turn off for me (I've listened to tons of death & black metal in my life, and still do), so I'm VERY curious now. I'll give it a listen in a few hours.
