Bob Mould has almost recovered from the first leg of the tour as he prepares for a show in Denver. “Granted, 45 years later, I don’t tour like that, but this first run of Sugar shows was pretty darn physical. Mould was already an underground legend by the time Sugar came together. “For the first three years of Sugar, I was out of my head,” says Mould. As someone who claimed not to be big into nostalgia, he says he enjoys seeing the lasting impact of Sugar.
