These 12 singers, plus one of 4 bonus contestants will perform on Tuesday
Aaron Marcellus of 'American Idol'
Hometown: Atlanta, GA
Notable For: Last year, Aaron Marcellus was Aaron Sanders and you may remember his Hollywood Week group performance with Robbie Rosen and Jordan Dorsey, who were both eliminated in the Top 24. Now he's back. With glasses! He was actually more featured last season, when he was included in commercials. Maybe the producers figure something subliminal will sink in?
