• The xx have already attracted the likes of Spoon's Britt Daniel and Courtney Love to their concerts, plus one audience member that Sim says, "if you'd told me when I was 15 that this would be happening. I might have had a panic attack." When they played at Paris' Point Ephémère earlier this year, "there was this figure sitting on a chair with no one else around him," Sim remembers. "I kept staring and thinking, 'Is that . . . that can't be?'" It was: Michael Stipe.
