He's more 'nasally' than Bruce, but yeah, this is probably the closest vocal cover I've heard.
I've always mixed feelings with these things. On one hand, it's really cool to pull off if you have the talent...and this guy is super talented (especially with someone as hard to mimic as Bruce). As a fan, that's cool to see. On the other, I wouldn't want to invest much time cloning someone else because that energy could be spent doing your own thing. If Bruce spent all of his time fixated on Ian Gillan covers, we would never have gotten the Bruce that we know now.
