If you're planning to attend the Rock the Bells concert tomorrow and want to know who's playing when, we've got you covered. The name that's most noticeably missing from this list is Santogold. Honestly, she was probably the person that I'm most excited to see live. And I'm bummed that she won't be here. But there's still a red hot line-up and lot's to enjoy if you're a hip-hop fan.
