Sometimes rock stars get laid off too. Jean Smith, half of the legendary Vancouver duo Mecca Normal, found that out recently when she was let go from her job at a clothing store. As it turned out, the job loss coincided with the 25th anniversary of her band, so she and partner David Lester decided it was time to hit the road, this time with an art exhibit, lecture and performance event called “How Art & Music Can Change the World.” They’ll be in Durham this Saturday at Duo Fest, an event celebrating two-piece rock bands hosted by locals Beloved Binge. Before embarking on the tour, Smith answered five questions for us.
