I'm not surprised at all that this sold out. It's been widely reported that this will be their (BSS's) last tour for many years. The demands of the member's main projects (Apostle of Hustle, Stars, Weakerthans, Fembots, DMST, Raising the Fawn, Metric, Feist, etc etc etc) just got too hard to coordinate. Add the inevitable backlash and a rather sensitive Kevin Drew...and you get extended hiatus.
So far on the tour, the band has been limited to seven people (Kevin, Brendan, Charles, Andrew, Justin, Ohad, and Amy) though Julie Penner has played the last two shows so hopefully she'll stick around for the rest of the tour.
