Isis has called it a day.
From Isis myspace page:
"ISIS has reached an end. It's hard to try to say it in any delicate way, and it is a truth that is best spoken plainly. This end isn't something that occurred over night and it hasn't been brought about by a single cataclysmic fracture in the band. Simply put, ISIS has done everything we wanted to do, said everything we wanted to say."
They plan on finishing this tour though so go out and see them at the Doug Fir on Wednesday.
