Ok, here is new version of me singing "Heaven and Hell".
I've been training distortion lately, so I thought I would like to try it. Now it sounds more that I like. I also didn't sing so loud this time and that helped too to get better tone. I forgot to sing the "On and on and on" part with ah vowel, but tone is better this time so it doesn't matter to me.
Give me your opinions, thanks.
