Julianna Barwick’s original "Vow," from 2011's The Magic Place, is made from a million layers of her voice that as a cocktail sound like one big aaaaahhhhhhhhhhhhh. It's a shower-clean, drumless palate for magic-duo Diplo and Lunice to step in to. Not sure how you make a remix with another guy. I imagine in this case maybe Diplo is like Timbaland and Lunice is like Danja. They hung out and had fun and dreamed ideas for awhile, Diplo bought dinner. Then, Diplo took his kid Locket to baby swim lessons while Lunice cooked up the beat's tumbles and stutters.
