Apparently, tonight’s Linkin Park concert at the Verizon Center has been canceled, as “vocalist Chester Bennington is ill and under doctor’s orders to refrain from performing.” C’mon, Bennington! What you should have done is taken the stage after making the crowd — who just saw the lead singer of the opening act be severely burned by pyrotechnics — stand around anxiously for two-and-a-half hours, then abruptly call off the performance mid-set while complaining of a sore throat and threatening to break up the band, causing a massive riot. Rock stars these days, they just don’t know how to do it.
