Aly&AJ - Chemicals React Live - Americans Got Talent

As soon as Aj started singing you could tell she was sick but im glad she still sung great :] Aly did amazing too! ^^

they sound perfect

:) Wonderful.

wow they are very good.Its hard to do a live performance

They are the best!

Love this song... love thir voices!

yeah i think aj has a soar throat or something, u can hear it - she isnt normally that croaky

She was, I remember reading it somewhere.

I miss this, how they used to be. When Insomniatic realesed they turned into totally different people, kind of pop and preppy. :/ I hope their next album sounds more like ITR.

Aly sound better in this concert..but both are equally pretty...AJ is like sick or sumtin ryte Go girls:)
