I don't know about you, but when I see an act like the Roots or Black Star performing live, I always hope that they'll bring out a special guest who just might happen to reside in the area. So if I lived in, say, Chicago and saw Mos Def and Talib Kweli last night at the House of Blues, I probably would have been crossing my fingers pretty hard (or yelling drunkenly) for Common to join them onstage for "Respiration." Sure enough, that's exactly what happened and thankfully for everyone not in the Windy City, someone got some pretty great footage of the performance. I'm starting to think that the trick to capturing intelligible footage at concerts is to stand in the back.
