I've been unable to get ahold of Memphis through her e-mail. Does anybody know if she's still available as an indy?

Well, when I sent her an e-mail two or three months ago to inquire about her rates, it took her awhile to respond. I assumed at the time that was an indication that she didn't check that e-mail address until she was "active"/on tour.

She handles all of her emails, travel plans, screening, etc herself, so I'm sure its just a matter of her being really busy.  Perhaps pm her here but I would just suggest being patient.

I found Memphis to be extremely responsive when touring (as in, answering within a few hours).

She once told me that she doesn't answer emails at that address when she is not actively touring.  So if she's taking a break for some reason, you probably won't hear from her for a while.
