Beyonce' & Jay Z recently confirmed that they are headed out together on tour!  It's their "On The Run II" Tour.   There's rumors of a Seattle show, BUT that has yet to be confirmed.  Confirmed is their show in Vancouver BC Canada on October 2nd 2018.  Those tickets will go on sale March 19th.

We're assuming there will be another announcement with some more tour dates for the West Coast.  And with Vancouver being on October 2nd, one can assume that the show in Seattle will around the first week of October.
