A few bands from the "Best Metal" thread. And Meshuggah.

Dysrhythmia - Barriers and Passages Fantastic, audible bass.
Om - Pilgrimage Just drums, bass and vocals.
Protest the Hero - Kezia Great bass player, sometimes buried in the mix.
Meshuggah - Nothing (and everything after it) Not exactly what you're asking for, but I think you'll find that the guitars... well, you'll see.

I should point out that none of these bands are similar to the bands you mentioned. I just went for quality bass. Meshuggah is probably your best bet, though you might not like the vocals. All of their albums are unique, so if you're listening to a track and you don't like it, try something from a different album.
