Being pedantic, I seem to recall the bass in SYL being tuned down like the guitars - so, the E is tuned down to the C, then the B is dropped to some unearthly frequency.
There are some songs on Alien where you can make out the subsonic rumblings.
That's crazy talk - we all know The Intense Humming Of Evil sounds exactly like Your Love Alone Is Not Enough, which also sounds the same as Europa Geht Durch Mich!
