i think the first one is, RATM - Killing in the Name, and the second one is Slayer - South of Heaven
Oh! Big thanks to you, man! It's Slayer!
But as for the first song, i've downloaded the Killing in the Name guitar pro tab, and it's not this song. In my file he is talking smth about Black Sabbath's riffs, maybe it's their song,,,
well, i don't really know much Black Sabbath riffs or names, so there i can't help you, or i could search some and see what i find
Thank you! It's really seems to be from Electric Funeral. Thanks!
