Corpsegrinder is a much better vocalist (although at least Barnes on early CC had the benefit of being brutal as hell. His vox on SFU are just shit), but Barnes was one of the best death metal lyricists ever.
listen to this shit, it's much better than that lounge thing...not just a parody though, theyre in it for more than the lulz http://www.antimi.com/mp3s/srs.mp3 It's Adam Pfeffer & Veronica Valenzuela covering CC's "Stripped, Raped and Strangled."
