LA synth-poppers Capital Cities have racked up a staggering *X Factor announcement voice* 111 million-odd views of their debut single Safe And Sound on YouTube.

And they've been partying hard ever since, landing themselves a Grammy nomination and a support slot on the North American leg of Katy Perry’s gigantic Prismatic World Tour. The band recently attended, and indeed played at, the ALT 98.7FM Penthouse Party concert series in Hollywood, and founding members Sebu Simonian and Ryan Merchant looked excellent.
Ticking numerous cool popstar boxes, you can take your pick from the burgundy skinny chinos, the black or white Converse All Stars, the plain black T-shirt (Merchant on the left) and the band T-shirt (Simonian on the right). And, of course, every musician should finish his look with mirrored Wayfarer-style or Clubmaster-style sunnies. Top of the pops.
