Since winning a best rap album Grammy for their 2012 debut The Heist, this Seattle duo hasn’t dropped much in the way of new product. August finally brought “Growing Up (Sloane’s Song)” and “Downtown,” the first snippets of a record Macklemore has been promising since January 2015, while November saw the release of “Kevin,” all about the ravages of addiction. Macklemore himself relapsed into drug abuse following his sudden rise to fame, but now that he’s sober again and enjoying life as a new dad, he should be ready to grab the mic and get back to business. As for Lewis, he reportedly used his fat recording budget to create textured sounds inspired by The Beatles, Queen, and Pink Floyd. One man’s oldie is another man’s come-up.
