Is that a necrophagist shirt I see Exospaciac? There one of the only death metal bands where I can actually hear the bass (only ash remains is an absolutely mindblowing song). And whoever mentioned Nile earlier, they're a great band but I don't think I've ever heard audible bass in their songs. Guess thats what happens in drop A tuning!
I got to see Necrophagist last fall with Dying Fetus. It was awesome. Everyone was so tired after DF that everyone just kinda stood around. Partially because Necrophagist were fuggin mesmerizing!!
That was probably me who mentioned Nile

I LOVE 'EM!!! The only time you can really pick the bass apart from the guitars is on Annihilation Of The Wicked, I think. In Sacrifice Unto Sebek, you can hear it all throughout, once you've gotten used to it, especially in the "Tua Ashemu/Rekhes Au Sebek" part.
I remember driving through Seattle at 2AM with my buddy in his convertible blaring Von Unaussprechlichen Kulten. With his stereo, you sure can hear the bass--it's
frightening! That has got to be one of my favorite albums...
On the other hand, Cannibal Corpse has taken to writing songs in Ab...and the bass is still really distinct. Has to do with the player, I think. Also in Nile, George, Karl, and Dallas are pretty dominant players and Chief, Jon, and Chris have all kinda gotten buried by them, you know? Damn...I really want to see them live!!
The Warwick Vampyre--I know Siedemann from 1349 uses one of those. Seen them...talk about a COLD bass sound. Damn it is metal!
