Fox has released a new trailer for the upcoming 10th season of American Idol. It showcases the two new judges, complete with Steven Tyler’s trademark falsetto-esque scream and Jennifer Lopez reminiscing about growing up in the Bronx. American Idol returns on January 19 and will air for the first time on Wednesdays and Thursdays. The biggest format change is the elimination of the round of 24, with the top 12 locked in at the end of Hollywood week.
