We're not sure what Kele Okereke's scowling about. Bloc Party's Sunday night show at the Kool Haus was one of early 2007's hottest bills and the crowd ate up the group's 16-song set. Maybe he's not scowling at all, but rather squinting. The lights that surrounded the group strobed and flashed enough to cause seizures for all the epileptics in the world. So a warning to epileptics everywhere, avoid the Bloc Party show.
