I listen to a ton of underground artists, and a lot of net audio heads as well. Many can compete lyrically and vocally with emcees like Eminem. But please, don't ever say Eminem isn't talented or good or even one of the best around. Because he is, his lyrics are dope along with his flow. Yes, there are better emcees undergound or on the net than him, but not many. Salvation is a dope audio head who could also murder many textcees as well. Not that I take much of this shit serious, but its easy to recognize talent. And I have to say my favorite underground artist is Immortal Technique. They're not totally underground, but they aren't very well known. But they're lyrics are amazing in every way. Download the song "Dance With The Devil" by them and you'll see why they are so dope.
