Mel B: I thought the band sounded great. Your vocals are spot-on. I did enjoy it. You got me. It was good. Howie: You have performances like somebody who’s been doing this forever. You don’t flinch. You owned it. You deliver. Howard: You guys owned this stage tonight. I’m very proud of you. I was worried about you. Sometimes your vocals can go off, but not tonight. Also, the way you move, the way you engage the crowd. To be 13 years old and to know how to do that — I don’t know where that comes from, but you’ve got real talent. I’ll make a prediction. You guys will get signed as a band to a record label. Heidi: You guys rocked Radio City Music Hall tonight like true professionals. We forget how young you guys really are because you have this vibe about yourselves.
