Shhhhhhhh. At first this was just a boozy rumor tossed around at PDX Pop Now, but now it is confirmed:

Thao & The Get Down Stay Down and Horse Feathers will perform tomorrow (Tuesday, July 28, doors at 8 pm) at the Woods. If you have yet to visit the lovely SE venue, now is your chance. Plus tickets are an affordable $7, which means you can chow down at Saburos before the show and just walk over.

It just keeps getting better, here is an update:
"There will be a special guest appearance by members of the Portland Cello Project joining Thao on some songs."
