Emil and Dariel perform 'Live and Let Die' on America's Got Talent 2014 Semi Finals (VIDEO)

Emil and Dariel performed 'Live and Let Die' on America's Got Talent 9 Semi Finals 2 on Tuesday, September 2, 2014.

They perform "Live and Let Die", and this fits their style of music perfectly. Almost too perfectly, as they aren't really doing anything new like they did with "Satisfaction". I almost wish they'd done something less in their wheelhouse, maybe taking a popular song from an unexpected genre and flipping it on its head. Don't get me wrong, this was still great. But I wonder if it's going to be enough to get them through to the finals. Heidi and Mel B give the duo a standing ovation.

Mel B says they just come out here and "smash it" every time, adding that they just sound amazing. She says they also need to keep the band, because their band is "hot". Howie says they were perfect and that the performance was perfect, although it felt like Paul McCartney didn't show up to his own concert (presumably due to the lack of vocals). He says he was kind of waiting for Paul to show up. Howard agrees, although first he reminds the audience that these two are 14 and 16, respectively, which he says is mind-blowing. However, he states that if they do advance to the next round, they should bring a vocalist to add to the performance, since it does feel like something is missing. Heidi loved the performance, but asks why they didn't bring their grandfather out with them like Howard suggested last time. They note that while their grandfather was honored by judge Stern's proposal, he said he was living his dream through his grandsons. The duo also note that their grandfather had open heart surgery which left him limited in his abilities, so they're dedicating this performance to him.

Now I'm thinking they might go through. They're almost too damn likable not to get a ton of votes. And it WAS a good performance, after all. I wonder if they'd be able to bring in an eliminated vocalist and incorporate them into the act like the judges suggested, or if that would be a violation.

But what did you think of Emil and Dariel?
