MUMFORD & SONS' THIRD STRAIGHT NO. 1: It was a year of departures for Glassnote -- Childish Gambino decamped to RCA, and Glassnote itself left Universal Music Group for a distribution deal with Kobalt's streaming-focused recorded-music division, AWAL. But it was also a year of renewal: Mumford & Sons' Delta topped the Billboard 200 in December, posting 360,000 equivalent album units in two months. "We defied the odds, and we're going to continue to invest in rock'n'roll," says Glass. Case in point: U.K. singer-songwriter Jade Bird, whose rootsy first single, "Lottery," from her upcoming debut album, topped the Triple A chart for three weeks and racked up 5 million streams. Glass hopes to tap AWAL's strength in data to grow those streams worldwide. "The next holy grail will be what we do in India, China and South America," he says.
