In what’s turning out to be a busy day for A Perfect Circle announcements, it seems as though they will also be playing at the Ottawa Bluesfest on the 10th of July.  This festival, which spans a couple of weeks is bringing a pretty amazing lineup of acts including Soundgarden, Huey Lewis & the News, Joe Satriani and Shpongle.  The official website seems to be having problems at the moment, but you can check details here.
