Last night, the first installment from Hollywood week, front-loaded its best talent by having the early-round audition standouts called on stage to perform individually, without knowing why. It was a very effective way to generate enthusiasm quickly – but as the installment ended, things got more ruthless, and more tense, as the judges started winnowing through the remaining 100-plus contestants. That process continues tonight, as Idol works to regain its footing, and part of its audience.
