Rapper P.O.S. is calling off his national tour because he needs a new kidney.
P.O.S. says in an online video both his kidneys are "garbage" and have been going bad since he was a teenager, but he'll need one new kidney.
He had planned to tour with a dialysis machine at night, but he must do it in a stable location, so he will call off the tour.
He says it's terrible to put out an album, "We Don't Even Live Here," and not be able to tour behind it.
