One Direction

What can you expect at this show from Simon Cowell–groomed U.K. boy band One Direction? Nonstop screaming, barstool serenades, cheeky bromance, and a million bucks’ worth of camera-phoneage. Not to mention “What Makes You Beautiful” and other maddeningly catchy boy-band anthems. Like it or not, 1D's rabid fanbase is the closest thing we've got to Beatlemania today, and for four days they are likely going to fill Staples Center with its most ear-splitting pitch of the year.
