Wow! I mean, Wow!
I'm not really into Heavy Metal, but you pulled it off. Damn man, extreme from the quiet man in the corner. The Lady's quiet and calm voice adds a nice texture to the song... it quiets the metal which eases the ears. I must say you and Lady have done an excellent job on this piece, my utmost regards to her and of course yourself as well.
If you're feeling daring again then I would love to hear your next Heavy Metal piece within the near future.
