Something about these 2 reminds me of...
 

....Stevie and Lindsey
Could Alex & Sierra be the next BuckinghamNicks?

Wow, what talent and chemistry they have! I found their performing together really captivating, and the judges validated this after every performance they did. They certainly have what it takes to have careers as Lindsey and Stevie have. Just hope the fame and the spoils that go along with it don't end up tearing them apart like it did to Lindsey and Stevie.

Saying the same thing about them - love their chemistry!

Yes
 

I told my husband as soon as we saw them (we've been watching since the beginning of the season) that they remind me of Lindsey & Stevie when they first started. Sierra though doesn't play the tambourine; she plays the piano on stage sometimes. They are very good, very talented. I wouldn't mind seeing them win or Jeff Gutt.

They won!!!!!!!!!!!:]
