I liked it! I had only heard your covers of highway to hell and rainbow in the dark, so it was nice to hear you in a lower range. While I was listening, I was scratching my head trying to figure out who your vocals were reminding me of and then it dawned on me "Ah, the singer of Killswitch Engage". Which might seem like an odd conclusion to come to, but when I hear his voice I think of opera, not sure why but I do and while I was listening to you the same thing popped into my head. It's something with the delivery of the notes and how you hold them that reminds me of that. Anywho, well done on the song!
