Billboard was reporting it first, but they didn’t have much info.  The blog out of Complex covers the preview in more detail.

But yeah, Missy Elliot dropped a record preview.  I’d give you my thoughts on it, but I haven’t heard it yet.  As soon as I do, I will promptly shit rainbows for a week and then tell you all about it.

I assume it’s absolutely epic.  Missy rarely disappoints.
