Onstage at the FADER FORT Presented by Converse, The-Dream had insane, light-up Marty McFly shoes. We had hoped to talk to him about those for a good 15 minutes, but after his performance an assistant had stored them in a car for safekeeping. So, instead, we talked about his songwriting, his penchant for curse words and his grandfather. We also asked him to elaborate upon his recent Twitter squabbles with The Weeknd, but he wriggled out of that like a politician.
