The cellist's name is Lori Goldston, and yeah, she is, in fact, a member of Earth's line-up when playing live and, apparently her work is very prominent in the new album as well (i haven't listened to it yet).
Earth's line-up according to their facemook page:
Dylan Carlson (guitar)
Adrienne Davies (drums)
Lori Goldston (cello)
Angelina Baldoz (bass)
So, i guess that means we won't be seeing Karl Blau on bass either...
Probably it doesn't matter too much, but the reviews for this album so far have been positive. Here's pitchfork's:
