Hey Jen,
Heaven and Hell is one of my most favorite Black Sabbath / Dio songs, so it is and will be hard for any band to cover it in a way that I like! Well, however, you did a great cover version!
Musicwise I easily liked it, but I was a bit surprised that I like your (female) vocals that much! You have a unique voice and while I usually don't like female vocals, you already know that I love your voice - ever since I saw that youtube video with you and Urban.
You sing this song with much emotion and passion, and apart from a few words (the last syllables) I consider your performance as really well done! Especially the fast part at the end of the song is great!
So, thumbs up!
Life in shades of art, tell us who we are
Sunlight and shadows, reflected in my heart
Life in shades of art, and every time we part
Sunlight and shadows, life is shades of art
